Toronto police are working to identify a man wanted in a sexual assault investigation in the downtown core.

The incident happened last Friday, at about 2:40 p.m., in the area of 100 King St. W., which is just west of Bay Street.

According to police, a man approached a woman he did not know and sexually assaulted her. Investigators said the woman was able to walk away from the suspect, but he allegedly continued to follow her. The victim then reportedly confronted the man and yelled at him to leave, police said.

The suspect, who is described as in his 30s, approximately five-foot-nine with a thin build, short brown hair, a beard, and a moustache, fled on Adelaide Street.

He was last seen wearing an orange hat, black sunglasses, a blue sweater, a white t-shirt, khaki pants, white shoes, and carried a blue crossbody bag.

Anyone with information is asked to contact police at 416-808-7474, or Crime Stoppers anonymously at 416-222-8477 (TIPS) or www.222tips.com.
