Criminal Law (Amendment) (Protection of Property) Bill

My hon. Friend has raised two issues. First, what about troglodytes? Troglodytes are people who live in caves. Many people live in caves. Indeed, when I was on holiday in Spain, I visited several towns in which the houses were made out of caves. Are such caves buildings? My hon. Friend has posed a very good question. I presume that if they had a built-on front wall built and possessions inside they would be a building, whereas a tunnel would not. However, there may be a building inside a tunnel—for example, a sub-surface underground station. That raises interesting questions. If the British Transport police wanted to apprehend an offender who was in the ticket hall and then leaped over the barriers and ran down the tunnel, what would be the powers of the constables chasing him? Would those powers switch between the moment they left the ticket hall and the moment they entered the tunnel? Under the Bill, they probably would.
