People in Desborough have been urged to make sure their cars and houses are secure after a spate of break-ins in the town.
About six cars – most of which were left unlocked by their owners – were broken into between April 5 and 13.
In the majority of the incidents, the cars’ glove boxes and boots were searched, and, in several cases, items were stolen. Items included tools, laptops and iPods.
Inspector Richard Tall said extra resources had been put into the area to tackle the problem, but urged residents to help prevent further crimes.
He said: “We would ask people to make sure they lock their car doors and shut the windows when they park up and remind them to lock the doors and windows of their houses.
“We also urge people to remove all valuable items from their cars and keep them out of sight in your house.”
The series of incidents in Desborough also saw one car vandalised and a house broken into.
Witnesses to these incidents, or anyone with any information about them, should call Northamptonshire Police on 101. Alternatively, information can be given anonymously to Crimestoppers on 0800 555111.
