POLICE in Herefordshire are warning car owners to beware of a growing crime problem.

Crooks are using electronic devices to steal cars parked outside their owners' home.

The graphic shows how they can get away with your car.

Police advise owners to keep car keys away from the front or rear doors in your home.

And if you have a keyless car key, put it in a faraday box or bag (lined with a layer of metal mesh to block the devices thieves use to get the frequency from your key).
