Toronto Police have released the security camera images of the suspect of a sexual assault investigation.

Investigators say a man entered through a woman's bedroom window through a ground-floor window of a low-rise apartment building in the Black Creek Drive and Trethewey Drive area.

She was sleeping when he is alleged to have sexually assaulted her. She woke up to find him sitting on her bed. He then fled.

He is described as black with short black hair. Anyone with information is asked to contact Toronto Police or Crime Stoppers.
