I unwittingly drove down a dead end in Dalston and used a factory entrance to turn round. I noticed a man in uniform filming me. About a month later I got a bill for £300, for trespassing on private property. I admit I used this dead end to turn round about three times over the last couple of months. I am not a liberty taker. If it were causing people inconvenience I would not do it. There are no warning signs anywhere telling you not to do this. Can you tell me if I have really broken the law and trespassed? I never even stopped the car. I was just turning round. I have now received a final warning letter, and a ‘fine’ of £150,for late payment. Surely these people are no more than racketeers?
