Police are looking for a man they say pretended he was a police officer to pull over and rob a female driver on Monday.

Police say the man was in a car with a blue flashing light on the dashboard. He stopped a driver around Upper Gage and Mohawk Road around 11 p.m. on June 13.

But he wasn't a police officer. Hamilton Police say he searched the woman's car and stole her wallet.

Officers say the suspect is a white male, 30 to 35 years old, very slim, clean cut and no facial hair, with short blonde hair in a buzz cut and gelled.

He wore black running shoes, pants that looked similar to a police officer's with a red stripe down the side, a collared shirt, no name tag and a type of badge worn high on his shoulder.

The vehicle was a dark Ford similar to a Fusion with four or five antennas on the roof and no markings.

Anyone with information should call Det. Christine Bezeau at 905-546-3873, or Crime Stoppers at 1-800-222-8477 or crimestoppershamilton.com

Police say if you're stopped and you doubt it's an actual police officer, ask for identification if the officer isn't in full uniform. If you're still in doubt, call 911.
