Hamilton Police believe two indecent acts, one of a man exposing himself and another of a man masturbating in public near children, appear to be the same suspect.
Police have released an image of a silver sedan believed to driven by the suspect wanted in a pair of indecent acts in Hamilton's east end.
The pair of indecent acts date back to July 28. One happened at 8:50 p.m. near Congress Court in the Rosedale neighbourhood, near Quigley Road and King Street East.
A man was seen masturbating between two parked cars near two young children, and was chased away from nearby parents.
In a separate incident at 9:30 a.m., an 18-year-old woman claims a man repeatedly whistled at her and later exposed himself to her in a nearby parking lot.
The suspect in both incidents is described as a 5'11" white man with a medium build and spiked hair, weighing 165 pounds and wearing a black dress shirt and dress pants.
