A 20-year-old prisoner who received two years behind bars for seriously assaulting a teenage boy has been convicted of another assault committed on the same night. Jack Dylan Clarke appeared in Albany Magistrate’s Court via video link from Albany Regional Prison last Thursday pleading guilty to common assault for punching a 16-year-old boy in the face. Police prosecutor Sgt Alan Dean told the court that about 3am on September 19, Clarke and two teenagers were drinking and playing pool at a Mt Barker home. After an apparent miscommunication about a photo on display in the room, Clarke “angrily” approached the victim who was sitting in a chair and punched him in the face. Magistrate Robert Young took in to account Clarke’s age and the fact he was already a sentenced prisoner when handing down a six-month prison term to be served concurrently. In Albany District Court in May, Clarke received a two-year prison term for grievous bodily harm for seriously assaulting the other teenage boy, 16, on the the same night. The GBH offence was committed moments after the common assault. “The victim got up from his chair and attempted to intervene (after the first assault) by approaching the offender and telling him to calm down,” State prosecutor Robert Clarke said in May. “The offender spun around towards the victim and punched him once to the right side of the face with a clenched fist.” The next day, the victim had a metal pate and screws inserted into his jaw at Fiona Stanley Hospital in Perth. By committing the assault, Clarke breached a conditional suspended prison order he had received for attacking his former partner and a police officer.
