Tiesha Booton attacked the woman in Atherstone in September last year.
Tiesha Booton, 25, from Nuneaton has been given a 12 month prison sentence suspended for 24 months after pleading guilty to wounding a woman in an unprovoked attack at a pub in Market Street, Atherstone in September last year.
She was also ordered to pay a £156 victim fee and undertake alcohol abstinence and monitoring for 45 days which will be electronically monitored.
She was sentenced on Monday at Warwick Crown Court.
Sergeant Adam Skelsey from the North Warwickshire Safer Neighbourhood Team, said: “Booton struck her victim over the head with a glass bottle in a completely unprovoked attack, causing a nasty cut.
"Fortunately, thanks to good work by PC Lauren Hughes and the police identification unit she was identified from CCTV and has now been brought to justice."
