A car loaded with hidden cameras is being used by police to capture thieves on film as they break into it.
Police have released footage from the car's camera
Dorset Police are parking the car around sites in Poole, with a fake satellite navigation system placed inside to lure would-be thieves.
They have appealed for the public's help in identifying one man seen breaking into the car last month.
Police have released film footage of the man, who has a distinctive tattoo, breaking into the car in Corfe Mullen.
The break-in happened in South Road at about 0220 GMT on Friday, 17 February.
Chief Inspector Glen Chalk said: "The footage shows the man breaking into the vehicle by smashing the driver's side window.
"He used a screwdriver to break the glass and stole a dummy satellite navigation unit from the dashboard and a handbag from the passenger's seat.
"The footage catches part of a very distinctive tattoo on his right forearm just above the wrist."
