THIEVES stole a satellite navigation system from an ambulance while paramedics were treating a man with chest pains in High Wycombe.

An ambulance crew was called to a house in Chairborough Road, at 9.40pm on Saturday.

While they were inside a house, a satellite navigation system was stolen from the ambulance.

A spokesman from South Central Ambulance NHS Trust said: "Theft and vandalism of ambulance service vehicles puts lives in real danger, it is despicable that anyone would do this kind of thing.

"Our highly specialised navigational systems are useless to thieves anyway as they won't function outside of our system set up. Valuable NHS money will be spent replacing stolen equipment."

Police released details of the theft today.
