Kingston Crime Investigation Unit detectives are investigating a theft and subsequent deceptions that occurred earlier this month.
Investigators have been told a credit card was stolen from a vehicle which was parked in Birdwood Ave in Parkdale during the early hours of 20 November.
The credit card was subsequently used at service stations and convenience stores in Chelsea Heights and Braeside on the same morning prior to 6am.
Police have released images of a man they believe may be able to assist with their enquiries.
He is described as between 20-25 years old, wearing a black baseball cap, blue and maroon Nike jacket, and a large black spacer earing in his left ear.
