A Smiths Falls, Ont., woman is facing charges of sexual assault after allegedly touching a disabled man in his apartment in September.

A woman entered the Smiths Falls apartment unit through an unlocked patio door at about 10 p.m. on Sept. 17, according to Smiths Falls police.

The victim was lying on his bed. The suspect approached and began touching his groin, police said.

The suspect prevented him from getting out of bed until a roommate stepped in. The roommate's arms were scratched and she was pushed into a wall by the suspect, police said.

The suspect then stole a pack of cigarettes and left.
