Police have reminded people to lock up their cars and close windows following a spate of thefts during the warm weather.
Each day last week at least one person in the county fell victim to opportunist thieves after leaving their car unlocked or their windows open.
Thieves stole a DVD player and radio from an unlocked car parked in The Rushes, Burton Latimer, overnight between July 21 and 22, one of a series of incidents across the north of the county in recent days.
The following night, thieves took a tool box, sat nav and cigarettes from an unlocked car parked in Wollaston Road, Irchester.
In the early hours of Thursday, July 25, a dog box, binoculars and jacket were snatched from an unlocked car parked in Gretton Road, Harringworth.
At around 4.45pm on the same day, thieves stole a tool box from an unlocked van parked in The Avenue, Stanwick.
And overnight between July 25 and 26, thieves stole a disc-cutter, glasses and cash from an unlocked van parked in Windmill Road, Irthlingborough.
Sergeant Matt Conroy, from the volume crime team at Northamptonshire Police, said: “Unfortunately this is a common problem when we have good weather. It might be tempting to leave a car window open so it is cooler when you need to use it, but an open window really is an open invitation to a would-be thief.
“We are seeing thefts from insecure vehicles every day at the moment, in all areas of the county. East Northamptonshire in particular has been hit especially hard.
“We are doing all we can to stop offenders but we would urge people to take the time to lock up their vehicles and to keep valuable items hidden from view. Please help us to make life harder for thieves and to help keep your belongings safe.”
