Waterloo Regional Police have released surveillance images of a man they’re seeking in connection with a sex offence on a Grand River Transit bus.

The alleged offence occurred Monday afternoon, aboard a bus around the Boardwalk plaza on Ira Needles Boulevard.

An 18-year-old woman told police she was touched inappropriately by the man, who she does not know.

Police describe the man as South Asian and likely in his 30s, with brown eyes and dark, ear-length curly hair.

He was wearing very light-coloured, fitted blue jeans, as well as a white T-shirt, a black, zip-up jacket and a dark leather belt.

Police say anyone with information should call them or Crime Stoppers.
