Thieves stole number plates from three cars that were parked in Berkhamsted streets.
A blue Citroen Saxo was targeted in Stag Lane between 9.30pm and 11.40pm on Friday, while a blue Volkswagen Golf parked in Marlin Close had its number plates stolen between 5pm last Thursday and 7.40am the next day. And the rear plate of a green Jaguar was taken in Sheldon Way between 10.30pm on Sunday and just before 9am the following day.
Anyone with information can contact police via the non-emergency number 101.
Motorists can safeguard themselves from this type of crime by fitting anti-theft number plate screws, which can be purchased cheaply from retailers such as Halfords.
