A woman chewed on the arm of a nurse attending a Westlife gig in an argument over a toilet queue.
Tamara Dalziel, 26, pounced on Michelle McLister, 38, at the concert at The SSE Hydro in Glasgow on May 28, 2019.
Dalziel had been aggressive towards Ms McLister, who was waiting on friends.
The attacker sank her teeth into Ms McLister, leaving her with a scar.
On Tuesday, Dalziel was found guilty at Glasgow Sheriff Court to assaulting Ms McLister to her injury.
The court heard Ms McLister and a relative had been helping a woman who was stranded.
The trio went into the toilet but Ms McLister waited outside of the cubical.
Dalziel stood behind Ms McLister and stated to her: “I’m not waiting on anyone, I’m going to the toilet.”
Ms McLister told the court in evidence: “She said ‘what you doing waiting there anyway?’ and I said I was helping a woman who was in the toilet.”
The pair continued to argue before Dalziel “became aggressive” towards Ms McLister.
She said: “The woman grabbed me by the arm and grabbed me by the wrists.
“She had her teeth in my arm and I pulled back with her teeth still attached in me.”
Prosecutor Heather Naismith asked: “Did she bite you on the arm?”
Ms McLister replied: “Yes.”
The pair were separated by security and Dalziel left the arena.
Ms McLister was given first aid at the scene and treated herself at home with paper stitches.
Ms Naismith asked: “Was the skin broken?”
Ms McLister replied: “Yes, I still have a scar.”
Dalziel put forward a special defence of self-defence.
Ms McLister stated “absolutely not” when asked if she provoked the incident.
Sheriff Neil Mackinnon told Dalziel that he was satisfied with the Crown’s evidence before convicting her.
Sentence was deferred until next month for background reports and Dalziel, of Kirkintilloch, East Dunbartonshire, was bailed meantime.
