The man behind the scheme is a long-time fan of speed cameras, the Chief Constable of North Wales Richard Brunstrom, nicknamed the Mad Mullah of the Traffic Taliban.
The volunteers have been spotted pointing speed cameras at passing cars in Colwyn Bay. If a vehicle is found to be over the limit a note of the registration is taken and the details of the car are then passed to the police and an advisory letter is sent to the owner of the car. No fine or penalty points are issued.
The force said the letters have no legal standing.
