This happened a long time ago and it is possible that the laws on clamping have changed since then: The parking at anchor house retail park, mile end road is for customers of Halfords. I bought something at Halfords and then I came out of Halfords to find that my car had been clamped; the clamper said he saw me on a camera leaving the retail park, I hadn't so I knew he was lying, however it was my word against his. I could have shown him my receipt from Halfords however I suspected he would just continue his lie and say "you left before or after going into Halfords". He said I could go to court if I wanted to contest the clamping release fee, however he would have to tow the car till the matter was settled in court (thinking about it now it may have been a bluff). To avoid hassle I just paid him the 100pounds, it was basically a mugging. Halfords should ensure the parking enforcement agents they hire are honest and act within the boundaries of the law, otherwise don’t hire them (even if clamping is no longer allowed the same thing can still happen with rogue staff issuing parking tickets dishonestly, for example).
