Police have released a composite sketch of a suspect who is alleged to have sexually assaulted a woman near a GO bus terminal in Newmarket in the early hours of New Year’s Day.

According to police, the 18-year-old victim was walking westbound on a pathway that runs parallel to Davis Drive from the station at around 3 a.m. when she was approached by a man who grabbed her, forced her to the ground and then sexually assaulted her.

The attack was subsequently broken up by another man who came upon the scene. Police initially said that man left the scene without speaking to investigators, however in a release issued on Monday police confirmed that the man has since come forward.

In the same release, police also noted that there was more pedestrian traffic in the area surrounding the GO bus station than would usually be expected as people returned home from New Year's Eve celebrations. 

"Police are appealing to anyone who may have seen the suspect or saw anything suspicious to please come forward with any information," the release said.

The suspect is described as male, between the ages of 30 and 50, about five-foot-nine with a lean build. He was last seen wearing a light-grey jacket, a black hoodie, a black neck warmer and black boots.

Police say they do not believe this incident is connected to a rash of sex assaults in the vicinity of the Upper Canada Mall in Newmarket this past fall.
