With temperatures forecast to stay colder over the next few days, officers are urging motorists not to de-ice their car by running the engine and leaving it unattended.
A car was stolen from Clare Street in Raunds this morning (Friday, January 19) after it had been left unattended to defrost with the keys in it.
Although the owner only left it for a couple of minutes and was able to see the back of the car from the house, it was enough time for someone to get into the vehicle and drive off.
The car, a Vauxhall Corsa, was taken at about 6.40am. Anyone who witnessed it, or saw anything suspicious, is asked to call Northamptonshire Police on 101, or Crimestoppers on 0800 555111.
