 Section 24 was supplemented by a section 25 which created new powers (for constables only) to arrest those suspected of "non-arrestable offences" in certain circumstances.Sections 24 and 25 were controversially amended by the Serious Organised Crime and Police Act 2005, which abolished the difference between arrestable and non-arrestable offences and substituted one set of police arrest powers for all offences, irrespective of the maximum sentence.Citizens' arrest was confined to indictable offences.
