They're aiming to speak to a man in connection to the recent theft.
Officers investigating the theft of £700 worth of fuel from a service station in Markham Vale are asking the public for help to trace the man pictured.
At 1.45pm on Monday 14 October a HGV pulled up at the Markham Vale service station.
The man pictured, who was the passenger in the HGV, entered the store, handed over a fuel card as security and the driver of the lorry filled up the vehicle with £700 worth of fuel.
The HGV drove off with no attempt being made to pay for the fuel and the card was found to have expired.
