In England and Wales, the sus law (from "suspected person", see below) was the informal name for a stop and search law that permitted a police officer to stop, search and potentially arrest people on suspicion of them being in breach of section 4 of the Vagrancy Act 1824.
The power to act on "sus" was found in part of section 4 of the Vagrancy Act 1824, which provided that:
every suspected person or reputed thief, frequenting any river, canal, or navigable stream, dock, or basin, or any quay, wharf, or warehouse near or adjoining thereto, or any street, highway, or avenue leading thereto, or any place of public resort, or any avenue leading thereto, or any street, or any highway or any place adjacent to a street or highway; with intent to commit an arrestable offence
"shall be deemed a rogue and vagabond" and would be guilty of an offence, and be liable to be imprisoned for up to three months. This effectively permitted the police to stop and search, and even arrest, anyone found in a public place on the grounds that they suspected that they might intend to commit an offence.
In order to bring a prosecution under the Act, the police had to prove that the defendant had committed two acts:
Two witnesses were required to substantiate the charge, which was usually two police officers patrolling together.
The law caused much discontent among certain sections of the population, particularly black and ethnic minorities, against whom the law was particularly targeted by the police—see racial profiling. The sus law had attracted considerable controversy prior to the early 1980s race riots (in St Pauls, Bristol, in 1980, and in Brixton, London; Toxteth, Liverpool; Handsworth, Birmingham; and Chapeltown, Leeds in 1981). In 1980, the House of Commons' Sub-Committee on Race Relations and Immigration began hearings into the law. In the case of the race riots, its alleged abuse was believed to be a contributory factor to those events. The sus law was repealed on 27 August 1981, on the advice of the 1979 Royal Commission on Criminal Procedure, when the Criminal Attempts Act 1981 received Royal Assent.
