A man was seen masturbating on the Kenilworth Stairs on the evening of May 19, and police are looking for a suspect and anyone who might've seen someone acting similarly there last month who hasn't yet told police.

Witnesses told police the man was on the section of the stairs that goes from the bottom of the access to the escarpment trails.

People commonly use the stairs for exercise, cycling and hiking, and police are "encouraging anyone using the trails and stairs" to report suspicious people and activities to police.

Hamilton Police Det. David Brady said the Kenilworth Stairs are more isolated than some of the other sets of stairs around the city, and police have increased patrols near the area since the report came in.

Police think the man is white and in his 30s with a medium build and short straight "dirty blonde" or light brown hair that comes just over his ears. He was described as being unshaven and wearing khaki plaid shorts with a grey t-shirt.

Detectives Brady and Christine Bezeau are working on the case and can be reached at 905.546.3873. People with anonymous tips can submit them to Crime Stoppers.
