A MAN was repeatedly stabbed after a Celtic supporter nicknamed Shamrock turned up at his home armed with a knife.

Patrick Sheils inflicted three knife wounds on his victim, who did not see a weapon, before telling him: “Have a good look because I have just stabbed you.”

The High Court in Edinburgh heard that Garry Donnelly, 49, looked down and realised he was covered in blood.

Sheils, 42, was originally charged with attempting to murder Mr Donnelly following the attack in Heathcot Avenue, Drumchapel, in Glasgow, on September 16 last year.

But the Crown accepted his guilty plea to a lesser charge of assault to severe injury, permanent disfigurement and to the danger of his life.

Unemployed Sheils punched his victim on the body, struggled with him, knocked him to the ground, put him in a headlock and repeatedly struck him with the knife.

He also admitted attempting to pervert the course of justice by washing clothing he was wearing at the time of the attack in a bid to remove blood stains and DNA.

Advocate depute Stewart Ronnie said that following an earlier altercation Mr Donnelly had been at home in his flat when the door buzzer went.

Sheils, who was wearing a Celtic top, told him: “It’s Shamrock. Get f---ing down here Donnelly.”

The two men got into a struggle and at one stage Sheils was thrown down stairs.

Police were called to the scene and discovered blood outside and found a bare-chested Mr Donnelly in his living room and noticed puncture wounds on his torso.

The knife attack victim was taken to hospital and was found to have three wounds to his chest and back and a chest drain was inserted. He will be left with permanent scarring.

Officers later saw Sheils and noticed that he had blood on both of his hands and he was detained. They went to the home of another man which Sheils had just left and found the washing machine was on and recovered blood-stained trainers.

A knife was also recovered by police after it had been found under a hedge, the court heard. The weapon was forensically examined and traces of Mr Donnelly’s DNA were found.

Defence solicitor advocate Liam Ewing said the night before the stabbing Sheils had been drinking with others when Mr Donnelly arrived and “started shouting and issuing threats”.

Mr Ewing said that Sheils with “what on any view was a grave error of judgement” decided to go the next day to find out what lay behind the threats and took a knife with him.

He will be sentenced next month and was remanded.
