Motorists who leave valuable goods on display in a Nottingham crime hotspot will receive a letter from the DVLA telling them to think about security.
The letter will advise them to take better precautions when parking.
A police operation is under way after cars have been broken into in the Lenton Triangle and crime prevention leaflets are being handed out.
Police officers and neighbourhood wardens have been warning residents of the risks of leaving things on display.
'Inconvenience and upset'
Thieves targeting vehicles particularly in Kimboulton Avenue, Cottesmore Road, Arundel Street and Rothesay Avenue.
Det Con Rachael North, from Central police station, said: "People sometimes do not think about the type of things that thieves will steal. Many offenders are opportunistic and will break into a car for as little as 10p.
"Leaving items such as laptops and satellite navigation systems on display is offering them to criminals on a plate.
"It only takes seconds for an offender to smash a window and be gone, often causing the victim hours of inconvenience and upset."
