A PRISONER who slit the face of a fellow inmate with a homemade blade has been jailed for three years.

Craig Duffy, 27, pounced on William Cairns in Glasgow’s Barlinnie jail on New Year’s Eve 2019.

The thug struck after Cairns entered his cell while collecting rubbish.

Duffy later tried to hide the blade - which had a handle made of milk labels - in the bin.

He pleaded guilty at Glasgow Sheriff Court to the assault to Cairns’ injury.

Sheriff Andrew Cubie also put him under supervision for 12 months when he is freed.

The court heard Cairns was allowed into the cell by a prison officer.

Prosecutor Hannah Sweeney said: “Duffy exited and slashed Cairns with a makeshift bladed weapon

“He struck him on the left side of his face behind his ear and along his jaw line.”

Cairns was taken to the prison nurse for treatment and his wound was glued shut.

He later refused to make a formal statement about the attack.
