A man was photographed riding a stolen bike down the Mall, among thousands of other cyclists after it was taken from a participant in the Prudential RideLondon cycle event, police have revealed.
Images of the man riding the £2,600 green Trek Madone 4.9 down the road which links Buckignham Palace with Trafalgar Square were taken by official event photographers.
He is shown wearing a safety helmet as he rides the bike, which belongs to a 42-year-old man taking part in the event, after it was stolen from nearby Green Park on August 3.
PC Charlotte Brierley, of the Cycle Task Force, said: "The victim was about to take part in the FreeCycle event when his bicycle was stolen. The theft took place in the middle of a very busy event and we are urging people who were there who may have seen anything to come forward".
"I want to thank the organisers and the wonderful crowd who made all the difference as we cycled by, helping to spur me on to finish the gruelling 100 miles in a respectable eight hours.
"Huge congratulations to everyone who took part
