Police in 14 Division are investigating a sex assault.
It happened at the Yonge-Bloor subway station around 5 p.m. on Wednesday.  

An 18 year old woman was grabbed and sexually assaulted by a man, then he allegedly followed her onto the train over to Bathurst station. That's where he exposed himself to her.

Police describe him as being a white man, in his late 20's to early 30's. He had a medium to large build and was of average height. He had a scruffy beard, round face and short reddish hair with curls or waves.

He was last seen wearing a dark coloured waist-high winter jacket, grey jogging pants with elastics around the leggings, and a reddish orange back pack.
