Any hurt or injury calculated to interfere with the health or comfort of the victim. Assault causing actual bodily harm is a summary or indictable offence carrying a maximum punishment of five years' imprisonment. The hurt need not be serious or permanent in nature, but it must be more than trifling (R v Miller  2 QB 282). It is enough to show that pain or discomfort has been suffered, even though no bruising is evident. Psychiatric injury (more than mere anxiety or fear) may constitute actual bodily harm (R v Chan-Fook  2 All ER 552).
