In practice
This is an either-way offence: it may be tried at the magistrates' court or the Crown Court. Mode of trial depends on the seriousness and the defendant's election. All suspects must be interviewed by officers trained in sexual offence investigation. Disclosure must be handled in accordance with the Attorney General's Guidelines. Consider a Sexual Harm Prevention Order application. The suspect must be cautioned in accordance with Code C PACE 1984 before any questions about the offence are put to them. Interviews must be audio-recorded (Code E) or, for indictable offences, may be visually recorded (Code F).
