Thieves have been targeting vehicles in Bridgend, stealing catalytic converters from the exhausts.
Two thefts have been reported to police in the past week and officers believe there are other victims out there.
Vehicle owners need to be vigilant.
They are urged to take the following simple measures to lessen the risk of being targeted.
•Keep vans in a well-secured garage wherever possible, and if no garage is available, in a well-lit area.
•Park vehicles in such a way as to make access to the catalytic converter difficult, including parallel with another vehicle and close to fences, walls and curbs.
•Don’t mount the curb when you park as it gives thieves easy access.
Anybody with information about the thefts is urged to contact 101 and give reference *
Alternatively, they can call Crimestoppers anonymously on 0800 555 111.
