The shocking picture that shows police will do ANYTHING to hide speed cameras from unsuspecting motorists

The police force headed by the "Mad Mullah of the Traffic Taliban" which has been accused of waging a "vendetta" against drivers has a new weapon - a speed camera hidden in a horsebox.

The stealthy ruse is North Wales Police's newest crackdown on speeding drivers and sees officers hiding in the back of the horsebox while parked up on a grass verge.

The force is headed by Richard Brunstrom who was dubbed the "Mad Mullah" after a serious of tough new measures to catch speeding drivers.

Mr Brunstrom has previously raised the prospect of speed cameras being hidden in cats' eyes. But despite his force's crackdown on motorists, road deaths and serious injuries are up by a third.

Last year he faced calls to quit after he showed pictures of a headless biker to journalists at a road safety seminar without telling the motorcyclist's family.

His 'Arrive Alive' speed cameras caught 55,000 offenders in 2007 including 19 police vehicles not answering 999 calls.

Arthur Roberts, of the pressure group People for Proper Policing, claimed: "This horsebox will be another serious distraction for motorists and doesn't really address road safety.

"It's another cynical way of raising revenue."

A spokeswoman for the police force said last week, when rumours about the hidden camera were rife: "As days get longer we can anticipate many more motorcyclists riding in North Wales.

"Tragically some of these will die or some will be seriously injured and in some cases excess speed will be a significant factor in these incidents.

"With our partners we are seeking to reduce the number of deaths and serious injuries to motorcyclists and other road users through education, rider awareness, engineering and enforcement.

"Our enforcement activity will increase as the days get longer, but we're not prepared to comment now on the precise tactics that will be used. We would ask that all road users obey the law and ride and drive responsibly."

Yesterday the horsebox was parked alongside the road at Maenan, near Llanrwst - a straight stretch with a 60mph limit but renowned for speeding.
