Toronto police are looking for the man alleged to have sexually assaulted a woman on Highway 27 at the West Humber Trail bridge.

The alleged assault happened Friday night around 9:30 p.m.

A 22 year-old woman was walking on the bridge and was approached from behind by a man with a bicycle.

It's alleged that the man caught up to the woman and sexually assaulted her, before riding off down the trail foot path.

The suspect is described as 5'6 with a medium build and a light brown complexion. He's thought to be in his mid to late 20s and may have had a chin strap beard.

The suspect also may have been wearing a red turban at the time with a blue shirt and spoke with a raspy voice.
