Constable Sunil Atmaram More, the accused in the Marine Drive rape case, has admitted in his statement to the police that he raped the teenager after threatening to inform her parents about seeing her in a compromising position with her friend.

The statement was recorded soon after the rape on April 21, at the Marine Drive police station. The case has since been handed over to the Bombay Police's Crime Branch.

Medical doctors who examined More after the rape confirmed that the constable told them virtually the same thing. The doctors said the constable was drunk when he raped the teenager.

According to More's statement to the police and the doctors' account, this is what happened: the constable was at the Marine Drive police chowky when a watchman from a nearby building complained to him that a boy and girl were behaving in an intimate manner on the rocks of Marine Drive, with two boys keeping a vigil for passers-by.

Where the two versions differ is on what happened next.

According to More's police statement, the watchman summoned the couple and their friends to the police chowky, where More drove away the friends and detained the girl.

According to the doctor, More walked down towards the rocks. Seeing the sight of uniform the boys keeping a watch ran away, and More asked the couple to accompany him to the chowky.

High level sources in the Crime Branch confirmed the sequence of events, but clarified that the watchman merely informed More about the couple.

More claimed his original intention was to arrest them under Section 110 of the Mumbai Police Act, which bars indecent behaviour in public; offenders are fined Rs 1,250 and/or face police custody for a day.

Instead, More changed his mind and told the boy to leave the place as he needed to take down some details from the girl.

'In my drunken state I had lost my senses. I forgot to do my duty and instead told the boy to leave the place immediately or else he would face dire consequences. After that I took the girl to the police chowky and raped her,' More is reported to have told the police. 'I put fear in the girl's mind that if she does not let me have sex with her I will let her parents know about her actions. I then forcefully raped her.'

More's pubic hair, nails and blood samples have since been sent for chemical analysis.
