Police are warning drivers not to leave their valauables on show after a spate of car break-ins.
Five cars were targeted overnight between Tuesday and Wednesday in and around Branch Road in Barkisland.
In each case, a window was smashed to get inside.
Several sat navs and a laptop were stolen.
Police say thieves will tend to target vehicles that are insecure and have valuables on display. They say sat nav owners should remove the devices and the holders from their vehicles when they park them.
They also advise drivers to park in well-lit areas. Anyone with information ring police on 101.
