In practice

This is an indictable-only offence: it must be tried at the Crown Court. The charging decision rests with the CPS (not police). Officers should photograph injuries at the earliest opportunity and again after 24-48 hours (bruising develops). Domestic abuse cases require completion of a DASH risk assessment. 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).
