His one-man crusade started last year when he was wheel clamped at a hospital - after being told to park his car there by a supervisor.
"I found the supervisor and he admitted liability but wouldn't take it off unless I paid £95.
"I didn't pay but took the law into my own hands and hired an angle-grinder and cut it off."
After investing in his own saw and creating a costume to disguise his identity he began looking for clamped motorists and his protest soon gained popularity.
... Sadly Angle Grinder Man's personal website is down (rumored to have been cut off by the British Goverment), but then again I suppose Batman's website is constantly being hacked by evil spammers, so it's probably best anyways....
