A thug fractured a man’s jaw with a punch from behind in an unprovoked attack outside a West Yorkshire pub.
A court heard the victim was knocked unconscious from the blow and had to have metal plates fitted to his face following the attack by James Patrick.
Leeds Crown Court heard Patrick, 34, was caught on CCTV carrying out the attack around midnight in the smoking area of a pub on the Corn Market in Pontefract town centre.
Jeremy Lindsay, prosecuting, said the victim was out with his girlfriend and was attacked shortly after going outside for a cigarette.
Mr Lindsay said the victim remembers little of the incident after being struck from behind.
Footage of the incident showed Patrick looking agitated walking from the rear of the pub as the victim had his back to him. Patrick then punched him to the side of the head before walking away.
The victim was taken to hospital and had to have an operation to have three metal plates fitted to his jaw and experienced problems with eating.
Patrick was arrested and initially claimed he struck the man because he feared for his safety as he believed he was going to be attacked.
When confronted with the CCTV evidence he changed his account of the incident.
Mr Lindsay said Patrick told officer that he “just saw red” and that he had behaved out of character.
Patrick, of Mill View, Ferrybridge, pleaded guilty to inflicting grievous bodily harm.
Martin Robertshaw, for Patrick, said his client was sorry for what he had done and had pleaded guilty at an early opportunity.
Mr Robertshaw said Patrick was currently out of work but was due to begin a job in the building trade as a welder and would be able to pay compensation to the victim.
Patrick was given an eight-month prison sentence, suspended for two months.
He was also ordered to pay £1,400 compensation to his victim plus £100 court costs.
Judge Tom Bayliss, QC, said: “This is an offence in which, in my judgement, you used unprovoked violence.
“You are seen to be looking agitated and you walked towards the complainant. The complainant has his back to you.
“You approached him and swung a punch at him, knocking him to the floor.”
