I had the Police visit and accuse me of causing a crash, when I was at university. They came when I was out and then a couple of days later, demanding to see my car.
I didn't have a car. I did have a blue Suzuki motorbike, with the same reg as the red Vauxhall Astra reported to have cut a skip lorry up, resulting in it knocking a traffic light down. I showed him the bike and he insisted that I should own up!
He wanted to know where I'd been the previous Friday and I told him St Abbs Head. "Oh, I suppose you can prove that, then?" he sneered.
Well, yes - 3 geology lecturers and 45 other geology students were on the coach with me. I suggested that the driver had crashed, come up with an excuse and made up a number plate. Apparently, that made me a smart arse.
I ended up getting a lecturer to write me a letter and went to the station with it and my bike documents. After a few minutes speaking to the bemused desk sergeant, he told me I wouldn't be hearing anything more!
