The Grimsby branch of builders merchant Jackson Building Centres was featured on BBC TV’s Crimewatch programme on Monday night after falling victim to fraud.
A man ordered industrial clothing and roofing materials, claiming to be buying on behalf of a company. But when the invoice was sent, the company denied all knowledge of the man or the order.
The fraudster drove a white Mercedes Sprinter van with false registration plates.
Police are looking into the possibility that the incident may be linked with similar crimes in Lincolnshire, Nottinghamshire and Thames Valley.
