Bhullar (68-67-68-65) saw it home with a sublime and error-free final round effort of seven-under 65 that took his tournament total to 20-under 268.
The 34-year-old Gaganjeet thus sealed his 11th international win and 10th title on the Asian Tour. The Indian also became the first player to register three wins at the Indonesia Open following his previous successes at the event in 2013 and 2016.
India's Rashid Khan (68-70-64-68), a two-time winner on the Asian Tour, shot a last round of 68 to enjoy a tied second finish at 18-under 270 along with Englishman Steve Lewton who carded a 64 on Sunday.
Khan had started the day in front with Thailand's Atiruj Winaicharoenchai but the strapping Bhullar was unstoppable and a man on a mission, making three birdies on the front, and four on the back - which included three on the trot from the 13th.
Bhullar showed no sign of Sunday nerves and put on a putting masterclass, holing brilliant birdie putts and crucial par saves, to record his first international victory since 2018. He has won more titles on the Asian Tour than any other player from his country.
The six-foot tall Bhullar, who originally hails from Kapurthala in Punjab, said, "I played like a champion tee to green and gave myself so many birdie opportunities. I was riding high on confidence and hit the ball really well. It was a great week, I had a lot of positive memories having won this tournament two times previous, that was definitely on my subconscious mind. The goal was just to go out there and give my 100 percent."
Indonesia has been a happy hunting ground for Gaganjeet as he has secured four titles in the country including his first win on the Asian Tour back in 2009. Pondok Indah Golf Course too has been a favourable venue for Bhullar since he won his last Indonesia Open title in 2016 at the same course.
Gaganjeet now joins an elite group of players who have won a National Open in Asia at least three times. The list includes Peter Thomson, Hong Kong Open and Indian Open; Jyoti Randhawa, Indian Open; Adam Scott, Singapore Open; Jumbo Ozaki and Tommy Nakajima, Japan Open; Lu Liang-Huan, aka Mr Lu', Philippine Open and Taiwan Open; and Miguel Angel Jimenez, Hong Kong Open.
"This is my first win after becoming a father and I would like to dedicate this win to my 11- month-old daughter. Also, after over two difficult years because of COVID it's just amazing the Asian Tour is back in this wonderful country. The support for me here has been incredible," added Bhullar, who has now climbed from 24th to 10th position in the Asian Tour Order of Merit after pocketing US$90,000 for his victory.
Rashid Khan made up ground over the closing holes with four birdies on the homeward stretch having started with nine straight pars.
Rashid said, "I couldn't make any birdies on the first nine holes, so it was a little difficult for me to come back after that. I had my first birdie on the 10th so I got thinking that I can make a few more."
Khan's joint runner-up finish moved him up from 50th to 27th place in the Asian Tour Order of Merit.
Ajeetesh Sandhu finished as the third Indian in the top-20 as he claimed tied 19th place at 11-under 277.
The 23-year-old Bengalurean ended two strokes off the pace with a total of 15-under 269, which was just one stroke below the medal bracket.
It was a heartbreaking end to Aditi's campaign considering she started the day in sole second position.
But it was nonetheless a massive improvement as she had finished tied 41st in the 2016 edition where golf made a comeback to the Olympics after over 100 years.
In the final round, she fired five birdies -- on the 5th, 6th, 8th, 13th and 14th holes -- against two bogeys on the 9th and 11th. The world number 200 Indian had her mother Maheshwari as her caddie.
Overnight leader and world number one Nelly Korda clinched the gold medal with a 2-under 69 that left her 17-under overall and a shot ahead of Japan's Mone Inami (65) and New Zealand's Lydia Ko (65).
Inami and Ko competed in a play-off to decide the silver and bronze medal winners in which the former emerged triumphant.
On the play-off hole (par-4 18th), Ko dropped a bogey, while Inami managed to hold on for a par in overcast and damp conditions.
Play was disrupted for a while by a tropical storm after the leading pack had completed 16 holes but soon resumed at the par-71 Kasumigaseki Country Club.
Aditi was in medal contention for a major part of the day but the two bogeys pulled her back while Ko surged ahead with a sensational nine birdies against just three dropped shots in her final round.
The other Indian in fray, Diksha Dagar, finished her campaign at tied 50th after managing her first sub-par round of the week, a one-under 70, which left her with an aggregate total of 6-over 290.
The Bengalurean, who has her mother, Maheshwari, on the bag, shot five birdies against two bogeys and moved to 12-under, three strokes adrift of leader Nelly Korda of USA who carded a two-under 69 in the penultimate round.
Four players -- New Zealand's Lydia Ko (66), Australia's Hannah Green (67), Demark's Kristine Pederson (70) and Japan's Mone Inami (68) -- shared the third spot with totals of 10-under 203.
Aditi fired five birdies and two bogeys on the day. She was three-under after picking up shots on fourth, sixth and seventh holes before bogeys on ninth and 11th pulled her back.
However, she made amends with birdies on the 15th and 17th to keep herself in the hunt for a historic medal.
The other Indian golfer in fray, Diksha Dagar, remained in the lower half of the leaderboard after an erratic one-over 72, her third successive over-par card of the week.
Dagar, who started from the back-nine, managed one birdie against two bogeys in her round on Friday.
This is Aditi's second Olympic appearance. She had finished tied 41st in the 2016 Rio de Janeiro edition.
Aditi said since she played only a few tournaments in May-June and also got infected by the coronavirus, has probably lost distance off the tee.
Yet her short game has helped her.
"I didn't really have my best, especially on the long holes with the long approaches where I wasn't as consistent. So, yeah, definitely it was a good day and I did not make as many bogeys as I could have," she said.
"My putting wasn't as good today as the first two days. So those couple par putts that were like the one on 12 and the one on 18, helped because I knew my putting wasn't that good today compared to the first two."
Aditi said she recoeverd from COVID-19 but it did affect her health
"It took a little bit of strength out of me. I was never this short. I was always short but not like 50 behind Nelly and 50 behind Nanna. But apart from the distance this year has been kind of the best I've had with my short game."
Aditi was also candid about the following golf back home.
"Nobody really follows golf as much. It's not that they know about it and don't follow it, it's just they don't know much about the sport to know that a major is more prestigious than the Olympics.
"And whenever the Olympics comes around it's always because we had a lot of sports where we were actually really good, like hockey, where we had, we used to win gold medals all the time.
"With golf being in (at Olympics) the second time I think people are a lot more aware and trying to follow it a lot more."
The tournament faces possible interruption and the final round could even be cancelled because of the forecast of a tropical storm on Saturday and maybe even Sunday.
The organisers have brought forward the tee times for the final round and have the option of playing on Sunday morning if weather permits.
They are hopeful of completing 72 holes, but if 72 holes cannot be completed, the tournament will revert to being a 54 holes tournament.
That would mean Aditi will have silver behind Nelly Korda's gold.
The 23-year-old rolled in five birdies, which included three in her last four holes, on yet another steamy day at Kasumigaseki Country Club to lie tied second on nine-under 133 with Danish duo, Nanna Koerstz Madsen (64) and Emily Kristine Pedersen (63).
Aditi, playing her second Olympics with her mother, Maheshwari, as her caddie, trails leader -- world no.1 Nelly Korda of USA -- by four shots.
Korda (67-62) at one stage was 11-under for 17 holes and looked set for a historic sub-60 score of 59 at the Par-71 course.
Diksha Dagar returned a 72 to share 53rd place on six-over 148.
Aditi kept herself in prime position of delivering a first-ever medal in golf for India with birdies on Hole Nos. 2, 5, 15, 17 and 18.
"The last three holes, I had a couple shots that were just a good number for me and I hadn't really had any short approaches all day, maybe just a couple," said Aditi.
With the competition faced with the possibility of being reduced to 54 holes due to impending thunderstorms over the weekend, the slightly-built Indian knows she needs to keep firing at the flags to ensure what would be a monumental podium finish for Indian golf.
"This whole week there's going to be so many girls making birdies, especially because the weather's warm and the conditions are favourable," she said.
"I think whatever holes I get to play, whether it's 54 or 72, I'm not really going to sit on anything, I'm just going to try and be as aggressive and make more birdies."
Her strong start in the women's competition has continued to attract plenty of attention on social media at home which Aditi hopes will make the sport more attractive for people in general.
She is dreaming of a medal but is experienced enough to know she needs to stay in the present.
"Oh, yeah, for sure," Aditi, who finished 41st in Rio five years back, responded if she was thinking of a podium finish.
"It's kind of like everyone's thinking about it. It's definitely at the back of my mind. But on the course, I'm not really thinking much about it. I'm just trying to hit the best shot I can hit.
"And hopefully people back home are watching it a lot more. I know a few of my friends are staying up to watch, which is cool. Olympics is huge.
"In a regular event people just wouldn't follow it as much, even if it was a LPGA event or a major. So, yeah, I think the buzz has been good so far."
Schauffele said grabbing the Olympic gold medal is the biggest win of his career. "I really wanted to win for my dad. I am sure he is crying somewhere right now. I kind of wanted this one more than any other."
India's Anirban Lahiri had a one-over in the final round and finished joint 42nd with three others with a five-under for the tournament. Udayan Mane was 56th with a one-over in the final round and a total of three-over.
Heading into the final round on a tied-28th position, Lahiri carded a one-over 72 in the final round to slip further to the tied-42nd spot with a total score of five-under 279 (67, 72, 68, 72).
Olympic debutant Mane too shot a one-over 72 in his fourth round to finish 56th in the 60-player field with a score of three-over 287 (76, 69, 70, 72).
Slovak golfer Rory Sabbatini grabbed the silver, one shot behind. The world No. 204 player surprised the course with an Olympic record-setting 10-under-par round of 61 on Sunday.
"To shoot 10-under on this golf course surprised me. I played nicely but still, 10-under is a tough score to make on this golf course." Sabbatini said.
"Just being here was an honour, to be a Slovakian representative. To be here and the medal is something that hopefully really gets the fires started to build golf in Slovakia, especially with the juniors."
Chinese Taipei's Pan Cheng-tsung clinched the bronze after a play-off.
The women's competition will take place from August 4 to 7.
The panel, led by the University of Edinburgh, showed that playing golf, which is good for both the mind and body, can also boost strength and balance in older adults.
The sport is also associated with good mental health and improving the overall health of those with disabilities.
It could be because golf is sociable and gets people outdoors to connect with nature.
It can also provide moderate intensity aerobic physical activity, and its health benefits are greatest for players (and spectators) who walk round the course rather than opt for a golf cart, researchers including Andrew D Murray, from Edinburgh's Physical Activity for Health Research Centre, explained.
While the risk of injury while playing golf is moderate, compared with other sports, golfers may be more at risk of skin cancer, he noted.
The researchers suggested that golfers should aim to play for 150 minutes per week.
Players should do warm-up or strengthening exercises to cut the risk of injury and use sun-cream and wear collared shirts or blouses to minimise the risk of skin cancer, Murray recommended.
In the study appearing in British Journal of Sports Medicine, the panel drew on a systematic review of the available published evidence (342 eligible studies) and discussions among an international working group of 25 experts in public health and health policy, and industry leaders.
While around 60 million people play golf at least twice a year, the sport is often perceived as expensive, male dominated, difficult to learn, and not a game for the young or those on the lower rungs of the social ladder.
The sport needs to be more inclusive and welcoming of people from all walks of life and ethnic backgrounds, the researchers said.
Staring at yet another bridesmaid finish this season, the Indian showed he would not be cowed under pressure as he holed a monstrous chip from outside the green for an eagle-three.
That eagle provided him with some relief as he would head into the last hole with a one-shot advantage over Australia's Anthony Quayle, who had earlier broken the course record with his nine-under-par 63 at the Natadola Bay Championship Golf Course.
Bhullar hit his approach shot straight onto the green on 18 and left his birdie putt just short of the hole. An easy tap-in for par for a winning total of 14-under-par 274 would soon confirm the 30-year-old as the newest winner of the Fiji International presented by Fiji Airways.
Quayle, who started the day two shots back of Bhullar, surmounted a late challenge when he stormed home with three birdies and two eagles in his back-nine.
However, it was still not enough to catch Bhullar on a day when the Indian showed great composure and mental courage.
Major winner Ernie Els of South Africa also staged a late comeback by closing with a 65 to share the third place with New Zealand's Ben Campbell.
The 28-year-old returned with a winning total of 12-under-par 276 to defeat Johannes Veerman (71) of the US by one stroke at the Linkou International Golf and Country Club.
He became the third Indian to win on the Asian Tour in 2017 and the second player from his country after Gaganjeet Bhullar to win the Yeangder TPC.
Local star Lu Wei-chih posted a 72 to miss out on the chance to win the Yeangder TPC for the second time in his career. Lu fired four birdies against as many bogeys to claim his best result since winning the 2016 Mercuries Taiwan Masters.
Sandhu, who missed out on a Tour card at Qualifying School earlier this year, edged a battling Veerman to the title after trading three birdies against one bogey.
Veerman, also searching for a first Asian Tour victory, almost forced a play-off when his eagle chip on the 18th hole hit the pin. He settled for runner-up, the second time in his career on the Asian Tour.
"I thought I would be a lot more nervous than what I was but after I got back to the hotel yesterday (round 3), I had so much of support from India. So many people, including people I don't know were messaging me. That really calmed me down," he said in an Asian Tour release.
"I'm proud of myself that I was able to focus on my own my game. I was just trying to hit the next shot the best that I could and I won," he added.
Bhullar was India's second-best performer of the tournament, finishing 19th with a total of two-under 286 (68-76-71-71).
Two pplace behind him was Shubhankar Sharma, who has total of one-under 287 (72-69-74-72).
Trump made the announcement on a Twitter post on Monday, but did not give any other details, reports The New York Times.
"Because of his incredible success and comeback in sports (golf) and, more important, life, I will be presenting him with the Presidential Medal of Freedom," the President tweeted.
On Sunday, the golf icon won his fifth Masters, the first major of the season played this week at the Augusta National course in Georgia, 14 years after his first victory in 2005. His earlier Masters victories came in 1997, 2001, 2002 and 2005.
The Presidential Medal of Freedom is the nation's highest civilian honour and is awarded to those who make outstanding contributions to national security or national interest, world peace, culture or other public or private endeavours.
The medal has been awarded since 1963, and is typically given to a dozen or fewer people each year.
Over the years numerous sports figures have received it, especially under the presidencies of George W. Bush, Barack Obama and Trump.
Last year Babe Ruth, Roger Staubach and Alan Page were awarded Presidential Medals of Freedom.
Woods will not be the first golfer to get the award; Arnold Palmer and Jack Nicklaus were honoured in consecutive years in the mid-2000s, and Charles Sifford, the first African-American to play on the PGA Tour, was honoured in 2014.
Woods has a longstanding relationship with Trump, an avid golfer. They own property near each other in Florida and have golfed together a number of times, both before and after Trump became President.
In February, Trump tweeted a picture of himself with Woods and Nicklaus at the Trump National Golf Club in Jupiter, Florida.
"Your spectacular achievements on the golf course, your triumph over physical adversity and your relentless will to win, win, win - these qualities embody the American spirit," Trump said on Monday evening as he bestowed the nation's highest civilian honour on Woods, 43.
The California native is number two in the number of major tournament victories, Efe news reported.
The distinction comes after Woods won his fifth Masters Tournament, marking a return to form after 10 years marred by scandal, a succession of injuries and addiction to pain-killers.
"This has been an unbelievable experience and... everyone here has seen and been with me for them, some of you for my entire life, and some of you for more than half my life," Woods said to a group that included many members of his family.
"You've seen the good and the bad, the highs and the lows and I would not be in this position without your help," he said.
Woods becomes the fourth golfer to receive the award, following Jack Nicklaus, Arnold Palmer and Charlie Sifford.
The original executive order that created the award, issued by John F. Kennedy in 1963, says the Presidential Medal of Freedom is meant for people who have made "an especially meritorious contribution to the security or national interests of the United States, world peace, cultural or other significant public or private endeavours".
Trump, himself a golf enthusiast, has long been friendly with Woods, who is designing a golf course for a club in Dubai that is managed by the Trump Organization.
There is a villa named for Woods at Trump's golf club in Doral, Florida.
"He's also a great person. He's a great guy," the president said after conferring he medal on Woods.
Last month, Trump signaled his intention to give Woods the award following the Masters triumph.
Previous Medal of Freedom recipients under Trump include NFL greats Alan Page and Roger Staubach and baseball legend Babe Ruth, who was honoured posthumously, as were Elvis Presley and Supreme Court Justice Antonin Scalia.
Nicholas Immesberger, 24, died on December 10, 2018 near the community of Port Salerno -- about 20 miles from The Woods Jupiter restaurant and bar, reports CNN.
The lawsuit filed on Monday blames Woods, who owns the restaurant where Immesberger worked as a bartender, and Erica Herman, who is listed in the complaint as the general manager of business and is Woods' girlfriend, for wrongful death.
The suit, brought by the victim's parents, said Immesberger finished his shift at 3 p.m., sat at the bar drinking and died in a single-car accident about 6 p.m.
The civil complaint says Immesberger had a blood alcohol level of .256, three times the legal limit. A police report has said that he was driving an estimated 70 mph in a 55 mph zone.
The suit alleges employees knew Immesberger attended Alcoholics Anonymous meetings and had another alcohol-related crash in November.
It also said that Woods and Herman knew of his addiction but were drinking with Immesberger a few nights before the fatal crash.
Immesberger's parents will speak to the media on Tuesday, CNN quoted a public relations firm as saying on Monday.
Woods is playing in the PGA Championship, one of golf's major events, this week and is scheduled to be part of a tournament news conference on Tuesday morning.
Sharma made the cut with a score of 66 (5-under par) in the second round after a par score i.e. 71 on Day 1. On the other hand, S.S.P Chawrasia and Gaganjeet Bhullar couldn't make the cut and ended the day at T-124 and T-154 respectively.
England's Lee Slattery was the leader as he sat at the top, tied with South African Erik Van Rooyen and Austrian Bernd Wiesberger at the score of (14-under par) after Day 2.
Sharma started the round in style with three birdies on the first nine holes. Things seemed even better when a birdie on the 11th hole finally gave him the belief that he could make the cut on a very tough day.
From 12-17 holes, Sharma was able to keep the projected cut score within touching distance and finally a birdie on the 18th, which was an amazing 45 feet putt, ensured that he will be going through to the final two days of the tournament.
Sharma had a bogey free round 2 ending with an overall score of 137 (5-under par) after day 2 of the event making a jump of 54 places to keep the Indian challenge alive. Sharma's scores are 71 (par) and 66 (5-under par) after round 1 and 2 respectively.
The day though belonged to Wiesberger. The Austrian bettered his first round score and scored 61 (10-under par) with the help of 11 birdies in second round. Wiesberger made a huge jump of 28 places to end at the top of the standings.
Slattery shared the first spot as he ended with an overall score of 128 (14-under par) after two rounds. Slattery picked up from where he had left and ended round 2 with seven birdies and a score of 64 (7-under par) same as his round 1 score. Erik Van Rooyen also ended with a score of 64 (7-under par) in each of the two rounds to be tied at 1st position alongside Slattery and Wiesberger.
The European Tour event will be brought live and exclusive to the Indian audiences by DSPORT on Day 4 from 7.30 p.m. onwards.
Sharma rallied against adverse weather conditions to finish a respectable tied 51 (T51) at the Open Championship in Portrush, Northern Ireland, in July. He will be looking to build on his momentum in Amsterdam.
Bhullar, on the other hand, will look to bounce back from his previous disappointing outing, when he finished T127 at the Omega European Masters, which concluded in Switzerland on September 1.
They will be joining defending champion Wu Ashun of China and last year's runner-up Chris Wood of England, both looking to return with a bang following a considerable period on the sidelines.
England's Sam Horsfield has bagged two top 10 finishes in his last four starts, and will definitely be a contender in Amsterdam.
The tournament will be broadcast live on DSPORT in India.
