A teenage student was subjected to a terrifying gang rape at the hands of three young men who threatened her with a knife and filmed part of her ordeal on a mobile phone.

The unsuspecting 19-year-old had gone to the home of Ammar Zahoor to chat and ‘chill’ with others she knew, but suddenly found herself alone with the 18-year-old and his friend Osman Ali, 20.

When the teenager tried to leave she was threatened with a knife and forced to perform a sex act on both men. At the same time one of them spoke to another friend, Abdul Sajid, on the phone and told him to come around to the house in Rochdale, Greater Manchester, for ‘some fun’.

The victim, who is white, was then taken upstairs and repeatedly raped by Sajid, and later by Ali and Zahoor, in a protracted attack she described as a ‘living nightmare’.
