Apparently there was an article in the paper the other night about someone who cut off a wheel clamp and was not prosecuted - not sure how he got away with it though.
Also this below from Evening Standard...
. .Three Londoners clamp a clamper van
by Matthew Beard. .Three Londoners spent £30 to make a dream come true - they clamped a clamper van.
"We wanted to give Westminster council a taste of its own medicine," said Mitch Webber, who masterminded the plan to buy a clamp and hit back.
Fellow conspirator David Brady added: "It was quite a bit of an adrenaline rush doing it, but we felt much better for it. As every Londoner will know, it is bloody annoying to get clamped."
Yesterday's Evening Standard carried the story of how the white van had to be towed away by Westminster council after it was mysteriously immobilised.
Today, Mr Brady, Mr Webber, and Julia Benwell, all executives at Tugboat advertising agency in Greek Street, said they had acted on behalf of Soho's many small businesses which are paying out a small fortune in fines.
"The last straw came when I watched the TV show Clampers. There was one sympathetic guy who gave motorists fair warning and another in the City who was intent on getting 100 tickets in the day. It was then I realised it was time to act," said Mr Webber.
"They arrive in their van at about 10.30am and issue a load of tickets to cars parked on residents bays, but no one around here, including the residents, knows where they can legally park."
When they spotted the white transit van on a yellow line in Soho Square during a routine "swoop", the conspirators went into action.
After waiting for the legal time limit to elapse, Mitch and David snapped on the yellow device while Julia took the photographs. They slapped a tongue-in-cheek penalty notice on the windscreen which read: "STOP. DO NOT ATTEMPT TO MOVE IT. YOU HAVE BEEN CLAMPED. There is nothing you can do. There is no-one to call. There is no one to go to for help."
A spokeswoman for Westminster council said police had been notified, adding: "Any unauthorised interference with council vehicles is taken seriously."
