Saskatoon police are looking for a suspect in a sexual assault.

Police released a composite sketch of the man Wednesday.

He’s described as Caucasian, 25 to 30 years old, about six feet tall and about 160 pounds with short light brown hair with blonde streaks.

He had facial hair on his chin, a scar in the centre of his left eyebrow and a snake tattoo on his hand and arm.

On Oct. 6, police were called to Royal University Hospital, where a 25-year-old woman was receiving treatment after she had been sexually assaulted.

The woman told police she had been walking in the south alley in the 300 block of 33rd Street West when a man pushed her to the ground and sexually assaulted her.

The man fled the scene and the woman’s friends drove her to the hospital.

Anyone with information about the suspect is being asked to contact Saskatoon police or Crime Stoppers.
