An undergraduate student from Kolkata has gone to police, saying an unidentified motorcyclist waylaid her in a dark alley in BTM Layout, south Bengaluru, groped her and tore up her T-shirt when she put up resistance.

The woman, who studies at a private college in the city, said the man began tailing her as she was walking back home from a local store around 10.15 pm on April 15. She had gone to the store to get mobile phone currency, she said.

She got scared and the man followed her into the alley which has no CCTV cameras. She said he groped her, hugged her and even tried to kiss her. He tore up her T-shirt when she resisted his attempts. He rode off when she raised an alarm, she stated in the police complaint on Monday.
