Cyclists are being put at risk of serious injury by saboteurs with a grudge placing drawing pins on their routes at the top of hills, a cyclist has said.

Tacks were spotted at the top of a hill in Headley, between Leatherhead and Box Hill, this morning.

Dan, a cyclist of 20 years from Walton who asked not to be identified further, but took this photograph today, said it seemed to be an increasing trend.

He said about a dozen cyclists on an organised ride, and maybe more, were punctured travelling between 25mph and 30mph, between Headley Heath and the Cock Inn pub on Church Lane, Headley, today.

Asked if the pins could be accidentally placed he said: "No, of course not. Wherever there's drawing pins scattered down a hill frequently its aimed at cyclists.

"It is definitely somebody out to cause trouble. 

"Generally I stay away from these areas where there's friction between cyclists and car driver.

"It is becoming more and more regular."

Last year a cyclist died in Richmond Park after falling off his bike, highlighting the dangers of taking a tumble at speed.

Dan said: "Luckily our group were punctured but all managed to stay upright.

"It is not right. If someone was out there and puncturing tyres there would be uproar."
