Champion free runner Tim Shieff defends stunt
A world champion free runner has played down criticism from Derby police after he posted a video of him high above the city's streets.
Tim Shieff, 24, said he had trained hard before making the film which included running along the top of the Assembly Rooms.
Police said it was dangerous and begged youngsters not to attempt free running.
Mr Shieff said he could understand people's feelings but added he practiced the moves and the route.
Professional free runner
The plea from the city police came after a video posted on YouTube filmed from a camera strapped to Mr Shieff's head.
The footage, from his point of view, shows free running across Derby's skyline.
Mr Shieff, originally from Derby and now living in London, has defended the video, saying he has been practising his skills for six years.
He now makes a living from the sport and travels the world to compete and also give talks.
Mr Shieff said: "I have trained for years, I have done every movement that was required for that one route and I did it slowly to begin with."
But police said it was dangerous and warned youngsters not to try the death-defying stunts.
Supt Gary Parkin said: "They are running across the rooftops of Derby city. I suspect they would only get one chance. One slip and they would fall and unfortunately if they fall they are going to cause themselves injury or even worse.
"I don't know what's going to happen to the people below them."
