Woman allegedly lured to sex assault TORONTO, July 14 (UPI) -- A University of Toronto student was charged Friday with using an elaborate ruse to lure a woman to a university building and then sexually assaulting her. Muhammad Umair Jafar, 21, of Brampton, Ontario -- who appeared in court Friday -- was also charged with choking the woman to overcome her resistance and disguising with criminal intent, the Toronto Star reported. The 19-year-old woman told investigators she believed an information session was being held in a room in the building Thursday afternoon, but it was empty when she arrived. She said a man wearing a medical mask came out of a bathroom, offered to help her and then asked her to help him with a repair he was working on. When she was in the bathroom, she said, she was knocked down and attacked. She eventually managed to escape. Police said they believe Jafar concocted the story about the meeting to get the woman to the building. They were trying to determine whether other women have had similar experiences.
