I hope that de-arrested you, rather than releasing without charge.
It doesn't take much for some idiot cops to arrest you.
I was driving near the Sale Sharks stadium when I came to a junction, a half-arsed roundabout, cleared it and went straight on. 5 minutes down the road, I was stopped by a "copper" who "arrested" me because he thought I was going too quickly round the roundabout.
I say copper, he was in plain clothes, as was the car. When he said I was going too quickly, I asked him if he had a calibrated speedo (bear in mind he was waiting to pull out onto the roundabout so was stationary. He said he didn't, and was driving alone, so didn't have any witnesses.
I asked for his shoulder number, he refused, so I wrote down his reg., which didn't please him.
I told him he could be any Tom Dick or Harry playing cops, how was I to know?
I made a complaint, but nothing much came of it, except that I was told he was off duty but still able to act in order to protect the public. Whatever that means.
But the whole point of my rambling story is that he did say he was going to de-arrest me.
At no time was I handcuffed. In any case, he didn't have any.
