A mental health nurse has dodged any time in jail after admitting to biting a security guard on the arm in a drunken attack outside a Townsville nightclub. John Richard Elliot was in handcuffs when he sunk his teeth in the arm of security guard Luke Colebrook. He was sentenced to 12 months jail but released on immediate parole after pleading guilty in Townsville District Court to assault occasioning bodily harm in public while adversely affected by alcohol.
