A child killer who sank his teeth into a prison officer has had his minimum 14-year jail sentence increased.
Jordan McCready, who is serving life for battering a 13-year-old boy to death, will spend an extra three months behind bars for the attack.
He left teeth marks on prison warder James Christie's hand after biting him when staff at Perth Prison intervened to control disruption.
Fiscal depute Michael Sweeney told Perth Sheriff Court : "He is a convicted prisoner in Perth, serving a life sentence for murder.
"He has no date of release at present. At 3pm on 10 April, 2021 the accused was seen shouting and swearing on the hall landing.
"Staff decided to place him back in his cell, to prevent disrupting other prisoners.
“As he was being escorted to his cell he was aggressive and abusive and was restrained to the ground by staff.
"While being restrained he continued to struggle with staff and bit the prison officer on the left hand. There was a bite mark but the skin was not broken."
McCready, 27, a prisoner at Perth, admitted attacking James Christie in the jail on 10 April, 2021, by biting him on the body.
Solicitor David Holmes, defending, said: "The punishment part of his sentence is 14 years. “Behaviour such as this will not go down well when he is seeking his eventual liberation.
"He had only recently arrived at the prison. He meant no personal affront to the officer. There was a problem with his medication and he was feeling unwell."
Sheriff Mark Stewart told McCready: "You have a formidable record for violence and have been involved in violence from a very young age.
"You are still involved in violent behaviour. Prison officers require to receive protection from the risks and dangers in the environment in which they work."
McCready was a teenager when he battered schoolboy Jon Wilson to death in 2011 as he was making his way home from a friend's house.
McCready, who was 17, was out on bail at the time of the killing having been freed despite carrying out an earlier attack on police officers.
After McCready admitted the murder in Kilmarnock, Ayrshire, it emerged he had been freed under curfew five days earlier for assaulting the officers.
At the High Court in Glasgow, McCready was given a life sentence after admitting Jon's murder, slashing a stranger and robbing a teenager of his mobile phone on the same night.
The court heard McCready had taken Valium pills and downed Buckfast and vodka before battering and fatally injuring the Kilmarnock Academy pupil.
The murderer stamped on Jon’s head so hard he bruised his own feet.
Passers-by heard "coughing and spluttering" and found Jon covered in blood and having difficulty breathing. His heart stopped just before paramedics drove him away.
Medics at Crosshouse Hospital managed to revive him but he had suffered brain damage and died the following day.
When McCready, who uses the name Cameron McCready, was picked up by police, he told officers: "I dragged him down a lane and battered the life out of him."
