Motorists in Sheffield have been advised to look at their parked vehicles through the eyes of a thief.
The challenge comes after four vehicles were broken into in Sheffield in a 24-hour period.
A rucksack was stolen from a vehicle in Manor, four wheel trims were taken from a car in Darnall and hundreds of pounds worth of tools were taken from a work van in the same area.
Thieves also smashed the rear window of a vehicle in a car park in Attercliffe to snatch a purse which had been tucked under a seat.
Inspector Ian Roberts, of South Yorkshire Police, said: “We don’t want people to leave items on view, but they also shouldn’t presume belongings in glove compartments or under seats are safe either.
“It’s important drivers park in well-lit areas and check their vehicles are locked. Basically, looks at your vehicle through the eyes of a thief.”
