A 26-year-old man allegedly approached a woman at the Guelph train station, grabbed her arm and exposed himself to her.

Guelph Police say the incident brought them to the Carden Street station around 7 p.m. Thursday.

They say the woman had been waiting for a train, and was able to break free from the man’s grip and get to safety.

The man, a Guelph resident, was arrested later in the night on charges of sexual assault, committing an indecent act and breaching his probation.
