A dad-of-two who snapped after years of abuse from a neighbour over noise stabbed the man's nephew near his heart with a pair of wallpaper scissors.

At the High Court of Glasgow 32-year-old James McCrimmon was convicted of assaulting Steven McCartney to the danger of his life on March 6, 2015 in Montraive Street, Rutherglen.

The jury ruled that McCrimmon had acted under provocation.

He was originally charged with attempting to murder 42-year-old Steven McCartney on March 6, 2015 in Montraive Street, Rutherglen, but convicted of the lesser charge.

McCrimmon lost his temper after his downstairs neighbour 58-year-old Robert Baird banged upstairs to complain about noise.

Bricklayer McCrimmon, who had a pair of scissors in his back pocket, went down to Mr Baird's home and kicked violently at his front door.

But, when Mr Baird refused to come to the door, McCrimmon knocked on the door of another neighbour Mr McCartney, who is Mr Baird's nephew.

Mr McCartney returned home to find McCrimmon banging on his door and a scuffle broke out during which McCrimmon stabbed Mr McCartney with the scissors.

McCrimmon claimed that McCartney took the scissors from his pocket and struck him on the head and neck. He said that as he tried to grab them back from Mr McCartney he stabbed him in self defence.

Mr McCartney was stabbed close to the heart with the scissors and McCrimmon had two wounds on his head and neck.

The court heard that trouble flared after Mr Baird moved into the four-in-a- block house in Montraive Street, Rutherglen, in 2012.

He constantly complained about the noise that McCrimmon's two young sons made in the house and would constantly shout, swear and bang up to tell them to be quiet.

In evidence, McCrimmon said of his years living above Mr Baird: “It was like walking on eggshells, trying to keep the kids quiet. You don't feel comfortable in your own home.”

He told the court he was in the house on his own, as his partner and son were out at football practice, when Mr Baird starting banging up and shouting.

McCrimmon, who is a bricklayer, added: “ I was clearing up the kids were making a Greek bath from cardboard for school. I put bits of cardboard in the bin, put pens away and put the wallpapering scissors they had been using in my back pocket.”

He told the court he was annoyed at the banging and added: “There were no kids in the house. There was no noise. I wanted to know why he was banging.”

Mr Baird, who is unemployed, said: “It was always noisy. I would complain. The kids played football and he had a loud voice. I'm deaf in one ear and it was still a problem for me.

“I would chap his door, but he just wasn't interested. He'd never answer me, just grunted and shut the door.”

Mr Baird, who witnessed the brutal attack on his nephew, said: “He was waving the scissors like a f***ing madman. He was f***ing mental that night – a madman. He called me 'a fat bastard.

“I saw James McCrimmon punching and kicking at my nephew that night. I f***ing hate him. I want him to pay for what he did.”

Mr McCartney said: “James McCrimmon was shouting and bawling. I never thought for a minute he had a big pair of scissors in his back pocket. He punched me and I punched him back and then he punched me in the face. He flung my hoodie over my head and I didn't realise he had stabbed me. I noticed the blood as I put the key in my door to go inside and then I collapsed.

“I lost a lot of blood. He just missed my heart, hit a main artery and punctured my lung. When the police arrived they were applying pressure to my chest.”

Mr McCartney denied ever having the scissors at any point.

The court heard that when police arrested McCrimmon had just showered and taken the scissors into the shower with him to wash the blood off them.

Both McCrimmon and Mr Baird have moved house since the incident.

Judge John Morris deferred sentence on McCrimmon, of Castlemilk, Glasgow, for background reports. He allowed him bail.
