CADILLAC (WWJ) – Police in Cadillac, Michigan are looking for help to find a man they say has been sneaking up behind women, touching their buttocks and running away.

Two separate incidents have been reported this past week. In the first case, a woman told police she didn’t know anyone was around until she was suddenly groped from behind while out walking in the morning at Lakefront Park.
