A 21-year-old woman was allegedly raped in Bengaluru by an unknown biker who gave her lift in the early hours of Sunday, the police said.

According to the Additional Commissioner of Police (East Zone) Raman Gupta, the woman, who is a college student, was returning home after a get-together. She took a lift from a biker, who instead of taking her to the designated place, took a detour to an isolated location.

“A man from whom she had taken a ‘lift’ made a criminal assault and allegedly raped her. We have registered a rape case and started an investigation,” Gupta said.

According to Gupta, the incident took place around 1 am on Sunday. The woman was found behind a truck near Hosur Service Road in HSR Layout, with only a red jacket covering her.

Her friends found her after they got her emergency message and location. They covered her and took her to a nearby hospital.

According to the police, the woman’s friends saw an unknown man standing there wearing only pants. He looked panicked and had visible injuries on his face. He fled as the woman’s friends tried to catch him.

ACP Raman Gupta said the woman has been admitted to a hospital and her condition is stable. Further details will be available after her medical test.

The police have registered a case under Section 64 (punishment for rape) of the Bharatiya Nyaya Sanhita (BNS) and launched a probe.
