Toronto police are looking for a suspect after an alleged sexual assault on a TTC bus. 

Police say the suspect approached a woman while both were riding the 100C Flemingdon Park bus sometime after 5:30 p.m. on Oct. 21. During the ride the man stood behind the woman and is alleged to have sexually assaulted her. The woman moved to another spot on the bus and saw the man behave similarly behind another woman, police say. 

The victim alleges she saw the same man riding the same bus and behaving similarly behind a third woman, on Nov. 13 at about 6 p.m.

Police released a photo and description of the suspect. He is in his early 40s, five-foot-seven, 180 pounds, with light brown skin and short, balding black hair. He was wearing a black jacket, black sweater, black pants and black shoes. 

Anyone with information is asked to contact 54 Division at 416-808-5400 or Crime Stoppers at 1-800-222-TIPS (8477).
