A woman headbutted a teacher and broke her nose during a rap concert.
Mhairi Walls, 39, attacked Marion Campbell, 54, at Glasgow’s O2 Academy, where the pair had separately gone to watch Scottish hip hop group Young Fathers.
A drunk Walls was asked by Miss Campbell to stop bumping into her before the assault, GlasgowLive reports.
The victim had her nose broken in two places in the attack, resulting in surgery.
First-offender Walls pleaded guilty at Glasgow Sheriff Court to assault to severe injury and permanent disfigurement.
The court heard Miss Campbell was at the concert with friends when she was approached by Walls on on November 30, 2018.
She repeatedly bumped into Miss Campbell and her friends while dancing to music.
Miss Campbell said: “Excuse me, do you mind moving out the way?”
Walls replied: “Aye, I f***ing do.”
Prosecutor Graham Macdonald added: “Walls then stepped forward and headbutted her making contact with the left side of Miss Campbell’s face.
“This injured her nose and her cheek bone.”
Walls, of Stirling, was later arrested and claimed the victim had been "annoying" her.
Fiscal Mr Macdonald said: “Miss Campbell's nose was found to be broken in two places and she underwent reconstructive surgery.
“Although there is no scar, her nose is displaced and squints off to the left.”
Sentence was deferred until next month for background reports by Sheriff Paul Crozier who granted Walls bail meantime.
The sheriff said: “You pled guilty to a very serious charge.”
