Prosecutor Sergeant Geoff Adams told the court numerous other guards attended and tried to escort Sbat away, but he responded by pushing at some and punching one to the face with a closed right fist.

Sergeant Adams said guards then tried to restrain Sbat as he ran to a nearby exit and when one attempted to intercept him, Sbat raised his elbow and struck him in the face.

Guards then took hold of Sbat and restrained him but he continued to react violently until his hands were secured and he was led to a holding area.

Barrister Tom Sawyer, for Sbat, of Greenacre, NSW, argued before magistrate John Doherty that the injury to the guard who sustained the facial breaks was not so serious to support a charge of recklessly causing serious injury.

This was opposed by Sergeant Adams, who produced a Department of Justice guide that defined injury and serious injury, and noted that Sbat also had two "relevant" prior court appearances.
