Motorists in the Fakenham area are being urged to be on their guard amid an increasing trend of vehicle thefts.
In the latest incident, raiders smashed a front window and stole property from inside a car parked at the town racecourse, between 3 and 5.30pm on Wednesday, August 6.
North Norfolk police commander, Supt Stuart Gunn, said the incident was an example of a rising number of opportunistic thefts. A similar trend is being seen across the county.
He said drivers of works vehicles, especially vehicles containing tools, were also at risk.
He added: “A lot of work is going in to prevent these crimes and catch the perpetrators.
“If you have a works van with tools, or a 4x4 or people carrier/transit, please be extra vigilant, especially overnight. Please don’t leave any property on display in your car.
“Please keep your eye out for criminals or suspicious activity and be very security conscious.”
Anyone with information about the latest theft is asked to contact police on 101.
