--It was about half past eleven when it happened. I was just walking out of the local library, having unsuccessfully sought employment there, when I saw a man walking across the road with the obvious intention of talking to me. I thought he was going to ask me the time. Instead, he said he was a police officer and he was arresting me. At first I thought it was some kind of joke. But then another policeman appeared, this time in uniform, and was left in no doubt.
