Tacks were found on to the Olympic race route according to police.

Similar sabotage in the Tour De France led to punctures for 30 cyclists, but swift action meant the Olympic cyclists were unaffected.

A police officer at the Scilly Isles, in Esher, told spectators the tacks were found in Elmbridge and Facebook reports suggested some had been found in Weybridge.

A Locog spokesman said: “Punctures are commonplace in road races, the route was checked before the race and continuously checked during the race with field of play marshals situated every few hundred metres.

“A small number of tacks were found on the road race and were dealt with swiftly by volunteers and police.”

On Saturday, police arrested a 54-year-old man in Leatherhead after he encroached on the cycle course as the cyclists approached just after 3pm. 

A police spokeswoman said: “Officers acted quickly and the incident did not impact on the race.”

On Sunday, a 42-year-old man was arrested in Dorking, and subsequently charged with racially aggravated harassment.

Chief Superintendent Gavin Stephens: “This has been an incredible weekend made all the better with the first Great Britain medal being won at one of our Surrey events.

“There were only two event-related arrests in Surrey over the whole weekend and this is testament to the fantastic spirit of the thousands of people who came out to cheer on the cyclists as they made their way through our county.”
