Shane Anthony Webster, 30 of Chestnut Avenue, was sentenced to 18 months' imprisonment, with a non-parole period of nine months late last month for assault occasioning actual bodily harm after an incident on December 1.

According to police, Webster, a trained instructor in martial arts, was in Summer Street buying a kebab when two male victims approached, aged 26 and 19.

Police said Webster punched the 26-year-old in the face and threw his kebab at 19-year-old before kicking him in the lower body.

The older victim raised his hands in a placating gesture before Webster punched him again to the right side of his face and he fell onto the roadway, unconscious, and Webster fled the scene. 

A community corrections report indicated his offending was linked to alcohol abuse and the incident had followed another disagreement earlier that day. 

Webster applied for bail pending his sentence appeal in the district court later this month but on Monday, magistrate David Day refused the request.
