An ambulance firm that delivers organs for transplant claims a police force is refusing to quash a speeding fine after a driver was caught by a speed camera.
M&L Ambulance Service, a private London firm, said Thames Valley Police was refusing to waiver Lee Schramm's £60 fine and three points on his licence.
Mr Schramm was driving at 36mph in a 30mph zone in London Road, Oxford.
A police spokesman said they had not heard from the firm to explain that Mr Schramm was on an emergency call.
He said all registered vehicle owners are sent a Notice of Intended Prosecution if their vehicle is caught being driven too fast.
Fines and points are then annulled if the journey was an emergency.
A firm has 28 days to inform police before a prosecution is launched.
The spokesman told the BBC News website that video footage from the camera showed Mr Schramm did not have the vehicle's blue lights on, so confirmation was needed to show he was on an emergency call.
Mr Schramm was driving a Ford Mondeo estate small private ambulance to deliver organs from Gatwick Airport to Churchill Hospital, Oxford, when he was caught by the camera.
A spokesman for M&L Ambulance Service told the BBC News website it had contacted police but that the fine and points had not been quashed.
He said: "My managers have been in touch with police and they haven't waived it at all."
The police spokesman added it was likely that the matter could be resolved if M&L Ambulances Service provided the required information.
