A prisoner was left with burns after being showered with boiling water by another inmate.
Violent robber Adam Smith went to the cell of Samuel Birch in HMP Northumberland and poured hot water from a kettle onto his face and upper body. A court heard he was left with blistered skin following the attack in August last year.
Now Smith, who was already serving a 90 month sentence for a violent robbery of a woman in Newcastle city centre, has had his time behind bars extended by 15 months.
