3. The Powers to Stop, Search, and Arrest

The police have extensive statutory powers to stop and search and to arrest a person in connection with the investigation of a criminal offence under various statutes, including the Police and Criminal Evidence Act 1984 (PACE 1984), the Terrorism Act 2000, the Misuse of Drugs Act 1971, and the Serious Organised Crime and Police Act 2005. This chapter examines the powers of stop and search before arrest; powers of arrest under PACE 1984; powers to search a person and his property after arrest; the power to grant street bail; and the right to liberty under Article 5 European Convention on Human Rights (ECHR 1950).
