VANDALS smashed up an ambulance while the crew was out on an incident, putting it out of action for six hours on Saturday night and Sunday morning. It is believed they were trying to steal the vehicle's satellite navigation system. However, these devices are built in to emergency vehicles and the only item the thieves would have been able to steal would have been the screen, which is useless without the rest of the system. Ambulance driver Brian Brooker told The Hunts Post he was completely disheartened to return to his ambulance and find the window smashed and the vehicle unfit to drive. Mr Brooker had been called to The Whaddons in Huntingdon after a man collapsed. Fortunately the man did not need to be taken to hospital, as the ambulance was out of action from 9.30pm to 3am.
