CCTV captured the moment a cocaine and booze-fuelled thug smashed a shot glass into the face of an innocent man at a casino - for 'eyeing up his missus'.
Lee Noble, who had sunk 15 pints and had taken cocaine, blamed his violent outburst on his victim, who was left permanently scarred.
The 39-year-old yesterday (Monday, February 17) started a six year jail-term for the 'horrific', unprovoked attack.
The true horror of the assault can now be revealed after shocking CCTV footage was released.
The footage, played in court, shows Noble sat at a table with his partner Kirsty Shaw, his victim and one of his victim's friends at the Grosvenor Casino at Parrs Wood, East Didsbury.
Noble didn't know his victim, who attended the same school as his partner.
They had been drinking in a nearby pub when they bumped into each other on October 27 last year.
The victim helped Noble find his partner, who had moved on to the casino ahead of him.
Initially, they were on 'friendly terms' as they sat and drank together.
Later, at around 2.30am, Miss Shaw and the victim started rowing.
Cameras in the casino lounge captured her twice throwing some of her drink over him.
She can be seen angrily gesticulating at the man.
"His recollection isn't great because of what he had taken," Kevin Donnelly, defending Noble, said.
"He perceived there had been an insulting remark or approach by the victim towards his partner and he reacted.
"Whether [the victim] did or didn't it doesn't begin to justify the way he [Noble] acted."
The footage shows Noble finish his drink before putting his jacket on. He is then seen walking around the table and launching a shot glass into his victim's face from a few feet away,
He then continues to be aggressive towards the victim's friend, who jumped up to defend him.
Casino security detained Noble until police arrived and he was arrested.
An officer claimed that on the way to the station, Noble said: "I glassed the f****r cos he was eyeing up my missus.
"I would have done it to his throat if I had to."
The victim suffered numerous cuts and bruises to his face, including a nasty gash under his right eye.
The court heard he was lucky to have not suffered more serious injury.
Noble, of no fixed address, pleaded guilty to wounding with intent.
Sentencing him Judge David Hernandez said: "This is a case of serious, unprovoked violence.
"The glass was thrown with considerable force into the face of a sitting man who you were a matter of feet away from.
"There has been no satisfactory explanation, and indeed there can be no satisfactory explanation for what you did.
"Your behaviour was no doubt affected by the drink and cocaine you had taken."
Miss Shaw was earlier given a community order by magistrates for offences relating to her role in the incident, the judge heard.
