Toronto police have released an image of a man wanted in connection with the sexual assault of a 15-year-old girl on a GO train Wednesday afternoon.

According to police, the girl was travelling on the Lakeshore East line when she noticed that a man who was sitting close to her appeared to be taking pictures of her with a cellphone.

As the train approached the Rouge Hill station, the man sexually assaulted the victim.

The suspect then followed the victim off the train a short distance before fleeing.

He is described as white, 25 to 30 year old, six feet tall, 180 lb., with short brown hair and unshaved.

He was last seen wearing a black winter jacket, beige pants, a beige baseball hat, construction boots and black sunglasses.
