Investigators have released surveillance camera footage of a suspect wanted in the gunpoint sexual assault and robbery of an 18-year-old woman downtown early in November.

Investigators say that on Nov. 5 at about 4:20 a.m., a woman was physically and then sexually assaulted in the area of Gerrard Street West and Yonge Street.

After the victim was assaulted, she told police that the suspect forcibly took her belongings.

The suspect was armed with a gun during the encounter, investigators said.
