We had one who used to spend a lot of time with local cops, he had a lovely GT Avalanche all striped up with yellow and green tape, a blue light on the front and everything. Only trouble was he was nothing to do with the County Ambulance Service, nor ST Johns, and when some locals tried to discover who he was and what he was actually doing it turned out he wasn't qualified, hadn't been CRB checked etc etc. The GT is still in our bike space taking up too much room. He tried to fight the case, but local Health Trust got very grumpy and he was eventually taken to court for various offences.
