Police in Bicester have launched a fresh appeal for motorists to remove valuables from their vehicles after 17 reported thefts over the last fortnight.
Vans and cars have been targeted mainly in the Kings End, Greenwood, Glory Farm and Bure Park estates.
Items stolen include in-car stereo systems, sat navs, power tools, cash, a laptop, a camera and iPhone chargers.
Most thefts have been late at night or in the early hours of the morning, with thieves picking door locks or smashing small side windows to get in.
Sgt Stephen Willis, from the Bicester Town Neighbourhood Policing Team, said: “In response to these incidents, officers and PCSOs from Bicester Police Station have increased high-visibility patrols in estates around the town, particularly after dark.
“We are keen to speak to anyone who may have witnessed any of these thefts or have any other relevant information.
“If you are approached by someone attempting to sell you any of these items, please report this via 101 as the likelihood is that they are stolen goods.”
In response to the recent thefts, the Bicester Town Neighbourhood Team will be holding community crime prevention events in the Launton Retail Park in Launton Road, Bicester, on Saturday, June 22; Sunday, June 23; Saturday, July 6; and Sunday, July 7.
