"Gates, welcome arches, posters, cut-outs, festoons have been vandalised ahead of our national president's rally. Gates have set on fire. Vehicles carrying our supporters are being stopped in many places," state BJP President Dilip Ghosh said.
BJP supporters and activists were threatened and harassed so that they could not attend the programme, he alleged.
"Despite all these, our supporters are active and the process of 'paribartan' (change) has been started," he added.
After high drama over denial of permission for facilitating the landing of Shah's chopper in Malda, the state's BJP leadership said that they finally received the clearance at two places in the district.
The BJP received permission to land the chopper at the helipads in Golden Park Hotel here and the one used by the Border Security Force in Malda district.
Acting on a tip-off about smuggling from Bangladesh, the Border Security Force troopers of border outpost Churiantpur in Malda district planned an ambush in and around the Indo-Bangladesh Boundary Fence (IBBF) area on Tuesday evening.
"The BSF recovered a bundle of 260 fake Rs 2,000 notes from the border area and handed over the seized notes to Kaliachak police station for further action," RPS Jaswal, Deputy Inspector General of BSF's South Bengal frontier, said in a press release.
"The troopers challenged a suspected smuggler who was about to collect the package thrown from the Bangladesh side of the fence but the suspect fled away taking advantage of the darkness," he said.
The BSF of the South Bengal Frontier has seized counterfeit Indian currency notes of the face value of more than Rs 36 lakh and apprehended five smugglers so far during 2017.
