A violent prisoner will spend 18 more months behind bars after pouring boiling water over a fellow inmate and kicking him in the head during a vigilante "jugging" attack.
Jaiden Dale Gardner's actions are said to have left the victim in "10 out of 10" pain.
ACT Supreme Court sentencing remarks, published on Thursday, show the victim was remanded in custody at the Alexander Maconochie Centre in March 2020 after he allegedly assaulted a woman Gardner knew.
