A woman glassed a man in the face after being told to butt out of a conversation.
Bethany Cox, 24, left Mark Cook, 29, with permanent scarring after she threw a drink in his face and then smashed the glass into his left cheek after he told her to “stop being nosey”.
Horrific injury pictures show Mr Cook with a huge scar on the left side of his face.
Jeremy Evans, prosecuting, said Cox launched the unprovoked attack after Mr Cook didn’t allow her into a conversation he was having with a woman about the breakdown of a relationship between his friend and the woman’s friend.
Cox, who was holding a half-filled pint glass of a Black Russian cocktail, threw the liquid in Mr Cook’s face, leaving him blind to her pulling her hand back and smashing the glass in his face.
Cox then walked out of the bar, placing the base of the smashed glass down as she left Matrix Bar in Grimsby, North East Lincs, in the early hours of March 30.
Mr Cook, who was bleeding heavily at the time, alerted bouncers and was taken to Diana, Princess Of Wales Hospital, Grimsby.
He was later transferred to Hull Royal Infirmary, East Yorks., where he needed 24 stitches.
Cox later handed herself into police after hearing from a friend officers were investigating the attack.
She admitted assault, but denied wounding with intent.
She was found guilty of wounding with intent following a trial at Grimsby Crown Court.
Mr Evans told the court Mr Cook was recovering well from his injuries and had no ill feelings towards Cox since the incident.
The court heard Matrix bar had introduced a new policy of serving drinks in plastic cups after 9pm following the attack.
Jailing Cox for four years, Judge David Tremberg said she had “lost control” and intended to cause Mr Cook serious harm.
Detective Constable Robert Laking, who led the investigation for Humberside Police, said after the hearing: “The jury has considered the case and found Bethany Cox guilty of wounding. This was a serious incident in which alcohol was considered to be a factor.
“Bethany Cox must now face the stark consequences of her violent actions that evening, which caused serious lasting injuries to another person.
“Humberside Police is committed to tackling violent crime and, as this case demonstrates will take action against those who behave in a way which threatens the safety of others.”
