Toronto police have released a composite sketch of a suspect wanted in connection with a sexual assault that occurred in the city's east end in the summer of 2012.

Police say that in late July or early August, at around 9 p.m., a woman was walking in the Victoria Park and Danforth Avenues area when she was grabbed from behind by a man and pulled into a nearby park where she was sexually assaulted.

The man also threatened to kill the victim, police say.

The suspect fled the scene on foot following the assault.

On Tuesday, police released a composite sketch of a suspect.

He is described as black with a dark complexion, in his late 20s to early 30s, approximately five-foot-eight, with a muscular upper body, long goatee and shoulder-length black dreadlocks with blond tips.

He was last seen wearing a black hooded sweatshirt, black shorts with blue stripes, and dark flip flops.

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