A spate of vehicle thefts has led to an increased police presence in Whittlesey.
Since the turn of the year there have been 40 incidents of vehicle thefts which has prompted Cambridgeshire police to send in more patrols to the town.
Police are unsure why the recent spate has occurred but are warning residents to make it harder for thieves to break in.
Many of the thefts have come from cars which are not secured properly which has led to items from inside being stolen.
The most recent thefts took place on Wednesday evening/Thursday morning (February 26 and 27) from two Mercedes and a Vauxhall in The Grove and Gildenburgh Crescent.
Numerous items were taken such as a Satellite Navigation system and a rucksack.
A police spokesman on the Policing Whittlesey Facebook page wrote: “A lot of frustration is being received about the volume of car crime in Whittlesey.
“Please be assured that the team and additional resources are doing all we can to catch those responsible.
“We are as frustrated as you but we won’t give up.
“Over 90 per cent of these crimes we are suffering is people getting into unsecure cars or by unknown means causing no damage.
“Please stick with us and continue to help us as you always have done by being vigilant, securing your cars and to continue passing on information.”
Residents are being urged to make sure they lock their vehicles and not leave valuables in there.
Owners should also keep their vehicles in a well-lit area or a garage.
To contact the police if it is not an emergency, call 101.
