THE BOSS of an advertising agency behind a "speed kills" radio campaign has vowed to go "all the way" in his fight against Macclesfield Police - after accusing an officer of "hiding behind a garden wall" to nab him.

Trevor Shepherd, 38, the managing director of agency Hartley Shepherd, was stopped by the policeman using a handheld device and received a £60 fixed penalty ticket, which carried with it three penalty points, for allegedly riding his 1000cc Suzuki at 46mph in a 30mph zone.

The executive, who had crossed the infamous A537 Cat and Fiddle road from Buxton on a Sunday morning ride, denies speeding and says the officer who caught him was unfairly concealed behind the wall.

Mr Shepherd, whose company worked on the recent £80,000 campaign for north west speed camera partnerships, said: "There is no doubt in my mind that this guy was hiding behind a garden wall and that is against the police's own code of practice. I have never been involved in a serious accident and this is just crazy.

"I have written to the chief superintendent at Macclesfield and I am waiting to hear back but I intend to go all the way with it. In the cold light of day there is no way that I was doing 46mph and the police speed gun was not type-approved to use against motorcycles."

Mr Shepherd, who lives in Marple, says he challenged the officer, saying he could not be seen by traffic from Buxton, but the constable had replied that he was clearly visible from the other direction.

Macclesfield police said they would not comment, because it looked likely that the case would now be going to court and was, therefore, sub-judice.

A Cheshire police spokesman said: "There is no requirement in law for an officer to be visible. As part of our best practice we would always try to be clearly visible when checking speed but the fact that a driver could not see an officer would not be a defence."

The Hartley Shepherd ad featured a Bruce Forsyth soundalike presenting an episode of Strictly Come Speeding.

"Brucie" commentates as a car speeds up and eventually loses control. It ends with the slogan: "Choose life. Slow down."
