In the video, the woman is seen speaking on her mobile phone when an unidentified man grabs her from behind and carries her off.
He then took her to an under-construction building in an adjacent road where he allegedly tried to molest her.
Several people were seen walking on the street but none tried to help her when the incident happened on the night of April 23 at Kathriguppe, a residential locality in south Bengaluru, but came to light only on Monday.
Recounting her ordeal, the woman said, “I started shouting, he tried to close my mouth, then I bit him to rescue myself. Reacting to it he hit me, then, I fell unconscious due to fear.”
He then fled from the scene leaving her lying unconscious.
“I was unconscious for about five minutes, by then he was not there. My bag and phone was still there,” she said.
She said police came and enquired with her about the incident after the CCTV footage emerged.
Manjula Manasa, chairperson of the Karnataka State Commission for Women, assured all assistance to the victim.
“Senior police officials should and will have to take action,” she said.
