CCTV captured the shocking moment a woman approached a complete stranger in a city centre bar and glassed him in the face.
The footage shows Katie Murphy emerging from the shadows and casually strolling up to the man who is drinking with friends.
She then 'swills' the drink at Joseph Walker, the dark-haired man on the right of the group, before breaking the glass in his face.
Murphy then exits the bar, leaving her victim wiping blood from a gaping wound just above his right eye.

The CCTV footage shows that few people in the bar seemed to notice what had just taken place, and they carry on drinking and talking as if nothing had happened, our colleagues at the Liverpool Echo report.
The CCTV was played at Liverpool Crown Court at the sentencing of Murphy, of Stonyfield, Netherton, in Liverpool last week.
The incident happened at Masquerade bar in Cumberland Street in Liverpool.
Chris Hopkins, who prosecuted the case, told the court that Mr Walker 'bled profusely and was left with a jagged wound. He was taken to hospital and needed four internal stitches and 10 external stitches above his right eye'.
Murphy, 30, claimed she was 'off her face' on drugs and booze when she launched the unprovoked attack on Mr Walker on October 10 last year.
The cocaine and alcohol-fuelled binge had begun the night before the incident at Masquerade bar.
Mr Walker will be left permanently scarred by the glass being smashed in his face, which only missed his right eye by the narrowest of margins, the court was told.
Murphy was reported to have 'blown two kisses' at the victim before leaving the venue.
In his victim statement, Mr Walker said the attack had left him with a visible scar to his forehead, and that he had become conscious of the way he looked.
He added: "I had a bubbly, happy nature before this happened, but I am now more nervous around people. I still don't know why it was me she did it to. Maybe it was mistaken identity, maybe she just didn't like the look of me.
"The injury was very close to my eye and it could have been a lot worse."
Mr Walker said he had 'forgiven' his attacker.
Mike Hagerty, defending, said Murphy accepted the victim of her attack was 'wholly innocent'.
He added: "The defendant has a significant mental health problem, including a diagnosis of paranoid schizophrenia, which is exacerbated by the use of drugs and alcohol. She has expressed regret and is remorseful."
Judge Recorder Richard Leiper QC told Murphy she had caused serious harm to Mr Walker by using the equivalent of a weapon.
He sentenced Murphy to 30 weeks in prison, suspended for 18 months after she after pleading guilty to causing grievous bodily harm without intent.
During that time, she was ordered to undergo a mental health and a drug rehabilitation programme, along with 120 hours of unpaid work.
