The baby Jiya, with her both legs and a hand fractured, had been admitted to a private hospital in Theragon near here last week, they said, adding the parents told the hospital authorities that the girl sustained injuries as she fell from her bed at their residence in Pimpri-Chinchwad town.
The girl's father Dastagir Hukkeri (28) was arrested on December 31 for allegedly thrashing his daughter as he was enraged over the birth of the third baby girl, police said.
Dastagir had two daughters from his previous marriage and remarried, apparently to have a son. However, his second wife too gave birth to the girl child.
According to police, the accused allegedly beat up Jiya with a rolling pin at his residence, police said, adding his wife kept mum as he had threatened her with dire consequences if she disclosed the torture.
However, she finally approached the police on December 31 and lodged a complaint against Dastagir and three of his women relatives, following which police arrested them.
