The power of arrest in section 41 of the Terrorism Act 2000 allows police to arrest a person upon reasonable suspicion of being a “terrorist”, which is defined in section 40. It also allows arrests to be made at an earlier stage than if there was a requirement for suspicion of a specific offence. There is no power of arrest under any of the other Acts mentioned.
