Police officers were called to a naked cycling event in Kent after members of the public complained about one rider caught in an "aroused" state.
The rider in question was called to one side and put his jeans on before being spoken to by police, according to the Mirror.
Organisers of the World Naked Bike Ride (WNBR) said the cyclist was removed before the ride began in Canterbury on Saturday (30 May).
One witness said: "Everyone was taking their clothes off to get ready for the ride. I heard gasps and I turned around – it was a horrible sight.
"It's fair to say he was overexcited and got aroused. It looked like he was enjoying the event a bit too much.
"One of the organisers went over to him and told him to put his trousers on while speaking on a walkie-talkie to police.
"The man looked sheepish when he was spoken to by the police."
Barry Freeman, an organiser for WNBR said: "We do not accept this behaviour and he was dealt with and removed before the ride started."
Chief Inspector Mark Arnold told the Canterbury Times that the event was peaceful although Kent Police is following on a complaint from a member of public.
He said: "The primary role of Kent Police was to facilitate peaceful protest and officers worked with organisers and partner agencies with the aim of keeping people safe and minimising disruption to the city.
"Generally speaking, nudity in public is not an offence where there is no intention to cause harassment, alarm and distress and therefore Kent Police did not have any grounds to stop the event."
He added: "One individual was spoken to by the protest organiser and stewards and he was required to get dressed and leave the protest, which he did. His details were taken by police, but no action will be taken against the man."
Last year, organisers received complaints about a man who turned up naked without a bike.
The London World Naked Bike Ride is a protest event in London raising awareness of issues such as safety of cyclists on the road, reducing oil dependence and saving the planet.
According to WNBR's website: "Join hundreds of naked compatriots in a free, non-sexual, fun bike ride!"
