POLICE have warned visitors heading to the county's hotspots by car to remove suction marks left from sat navs before leaving their cars, in a bid to stop thieves.

In an online police alert, the force explained that this time of year is when car thieves are most likely to strike.

"Even a jacket left in the back of a car can tempt thieves to see if there is anything in the pocket. Wipe away any suction marks from sat-navs and double check the vehicle is locked."
