Wagon drivers are being asked to remain vigilant after a spike in thefts at laybys off the A66.
Police said four vehicles were broken into last week whilst parked in laybys off the busy main road, near Barnard Castle.
During these incidents, the suspects stole large amounts of fuel as well as property within the wagons.

Sergeant Angela Drasdo, from Barnard Castle neighbourhood team, said: “Wagons are increasingly becoming an easy target for opportunistic thieves due to the huge amounts of fuel they carry.
“We want drivers to remain cautious and step-up security measures to prevent further thefts.”
Police urged drivers to never leave keys in the ignition, close windows and doors, and store valuables at home.
