Assault occasioning actual bodily harm is a specified offence for the purposes of chapter 5 of the Criminal Justice Act 2003 because it is a specified violent offence. It is not a serious offence for the purposes of that Chapter because it is not, apart from section 225, punishable in the case of a person aged 18 or over by imprisonment for life, or by imprisonment for a determinate period of ten years or more. This means that sections 227 and 228 of the Criminal Justice Act 2003 (which relate to extended sentences) apply where a person is convicted of assault occasioning actual bodily harm, committed after the commencement of section 227 or 228 (as the case may be) and the court considers that there is a significant risk to members of the public of serious harm occasioned by the commission by the offender of further specified offences.
