A convicted child killer attacked a Perth Prison guard after he refused to serve him his breakfast cereal.
Lifer Jordan McCready threw a carton of milk at officer Edward Robertson during an early morning strop in his cell.
It is his second conviction for assaulting a member of prison staff this year.
Earlier this summer, McCready admitted sinking his teeth into a guard’s hand during a row over medication.
The prisoner, who was jailed in 2012 for the murder of 13-year-old Jon Wilson, appeared via video link at Perth Sheriff Court and admitted the latest assault on June 1.
His solicitor described the incident as “a storm in a cereal bowl.”
Assaulted with milk carton
Fiscal depute Matthew Kerr told the court that prison staff were carrying out their routine morning prisoner check at 7.10am.
Mr Robertson went to McCready’s cell to bring him milk.
“The accused was standing at the door and asked to get his cereal,” said Mr Kerr.
“He was told to wait until the numbers check had been completed.
“Mr McCready became furious and threw the milk carton at the prison officer, striking him on the head.”
Mr Kerr said: “The accused’s cell door was closed and the matter was reported to police.”
Solicitor Paul Ralph, defending, said: “This was literally a storm in a cereal bowl.”
He said McCready had been already been punished inside the prison.
His client is not due for parole until 2025, Mr Ralph told the court.
Sheriff Craig McSherry sentenced McCready to eight months but the term will run concurrently alongside his life sentence.
Life sentence
In June, he was handed extra time behind bars for biting a prison officer’s hand as he tried to restrain him.
For that, he will serve another three months in jail when the punitive part of his life sentence – 14 years – ends.
McCready was 17 when he was jailed for the murder of Kilmarnock teenager Jon Wilson.
He admitted killing the boy as he made his way from a friend’s house.
The High Court in Glasgow heard McCready – who had been drinking vodka and Buckfast and taken Valium – attacked Jon near Kilmarnock’s Queen’s Drive on September 4 2011.
The second year Kilmarnock Academy pupil was found to have irreversible brain damage and died the following day.
