Terrorism Bill

The hon. Gentleman is floundering, so perhaps I may be of assistance. The police can arrest someone if they have reasonable grounds to believe that they have committed an offence. That does not have to be based on admissible evidence. If someone was held for two months at Paddington Green police station and, in his 15th interview, named a particular individual, the police could arrest that individual because they had reasonable grounds to suspect that he had committed an offence. However, that would not be evidence admissible in court. I hope that that makes it clear.
