A police warning has been issued to motorists in north Derbyshire following a spate of thefts from vans.
Over the last month 20 thefts have been reported to Derbyshire Police with offences in areas including Dronfield, Coal Aston, Eckington, Killamarsh, Clowne, Barlborough and Shirebrook.
Inspector Rob Bowns, who is in charge of the community safety and vulnerability unit for Derbyshire Police's north division, said: “Enquiries are currently being carried out into these crimes and residents are urged to report any suspicious activity to police.
"Patrols are being carried out and officers are speaking to motorists, particularly van owners, about boosting their security.
“We would advise people to remove all valuables, including tools, from vehicles overnight and to store them securely.
"Drivers are also urged to double check that vehicles are locked, the windows are up and any alarms are activated, even if they are leaving their van for just a short time.
"Motorists are also advised to wipe away any visible marks left behind by a phone cradle or sat nav and to park in busy, well-lit areas, if possible covered by CCTV.
"If it is absolutely not possible to remove tools and valuables from the vehicle completely, make sure they are out of view from passers-by.
"Consider parking with the rear or side doors obstructed to make entry more difficult and security mark all of your valuables to help make them easily identified and traceable. This also makes them less attractive to thieves.
"Take photographs of tools and equipment, and record the serial numbers as this can also help items to be traced back to their rightful owner.
"Remain alert and report any suspicious activity to the police."
Anyone with information on those responsible should call Derbyshire Police on 101.
