I was held along with a few other people on a train when some nut job decided to vandalise the train. This was a few years ago now, the BTP (British Transport Police) boarded the train carriage I was in and asked us all to remain seated. The culprit was identified, cuffed and removed from the train whilst an officer went round asking people what they saw. When he reached me I said I was sorry but asleep for most of the journey and he moved on. Once everyone had been spoken to we were allowed to leave.
