The 21-year-old woman who was allegedly molested inside a moving car late on Tuesday had tried breaking open some of the windows in a desperate bid to raise the alarm and force the driver to stop, police said.

The woman was returning home to Maheshtala, in South 24-Parganas, with two men and another woman after attending a birthday party in Jadavpur when she was allegedly molested.

The accused could not be arrested till late on Thursday.

The police had on Wednesday traced the car to a spot in the Lake police station area. The left side glasses of the car — black Jeep Compass — had marks of damage. “We have sought details of the owner of the car from the public vehicles department,” said an officer.

The woman is said to have told the police that she didn’t know the two men, one of whom was at the wheel. They were friends of the other woman in the car, the police said.

The complainant has told the police that the two youths had molested her and refused to stop the car while doing rounds across south Calcutta. She tried breaking open the glass so she could alert passers-by. She said she texted some of her friends and even sent the GPS location to a few so that they could help her.
