4x4 owners urged to weld on their catalytic converters after spate of thefts in Milton Keynes

Police say there has been a spate of thefts of catalytic converters from cars with higher ground clearance parked all over the city.

Cars particularly targeted have been Honda Jazz, Toyota Prius and Toyota Auris.

Police are advising the vehicle owners to consider added security steps to help safeguard their catalytic converters;

They are asking people to park in their garage if possible.If not, they should try to park next to a high kerb or other area that restricts access underneath the vehicle on the side where the exhaust is fitted.

"If possible park in a well lit area or consider security lighting. Consider installing a CCTV system to cover your vehicle as a deterrent," said a police spokesman.

He added: "If your catalytic converter is a 'bolt on', it is possible to have the bolts welded shut. Or consider fitting a specialist protective cover or clamp to your vehicle to make life more difficult for an offender. Contact your vehicle dealership for options."

Another option is fitting a specific catalytic converter alarm to warn of any tamper attempts. Some alarms can send a text message to your phone and activate a siren and flashing lights. If possible choose a Thatcham approved product www.thatcham.org, advise police,

Owner can also Identify/etch their converter, permanently marking it catalytic converter to make it less desirable for criminals to steal and sell on.

"The RetainaGroup offer a kit consisting of a virtually indestructible sticker, metal marking fluid and a window sticker (to warn thieves that the catalytic converter carries an identification mark). Each mark contains a seven digit code and a 24 hour telephone number for the International Security Register who store the code against vehicle details," said the spokesman.
