Toronto police are warning the public of a potential sex offender.

A 14-year-old girl told police she was walking in the Jane St and Weston Rd area early Tuesday morning when she was approached by a man driving a newer, black four-door car.

Police say the man asked the girl for directions, and then exposed himself.

The suspect is described as white, unshaven with short, black hair. He was last seen wearing sunglasses.
