A VIOLENT thug slashed a man on the face and neck when he refused to give her a cigarette then laughed and bragged about it afterwards.

Tracey Dobbie, 22, launch a “completely unprovoked” assault on Arthur Machnowski Westmuir Street, Parkhead, attack leaving him scarred.

Callous Dobbie was heard laughing afterwards then boarded a train shouting about how she had slashed someone.

A media appeal lead to the police getting information and viewing CCTV of the incident and Dobbie in the local area.

Her boyfriend later told police he was with her on the day of assault and she was identified from the footage.

On Friday at Glasgow Sheriff Court, Dobbie pled guilty to assaulting 33-year-old Mr Machnowski on May 13, last year to his severe injury and permanent disfigurement.

Procurator fiscal depute Lindsay Docherty told the court Mr Machnowski was standing with a friend on Westmuir Street having cycled home from work.

Dobbie and her boyfriend walked by and she stopped to speak to Mr Machnowski.

Miss Docherty said: “Dobbie asked Mr Machnowski for a cigarette to which he replied ‘no’ because he only had one left.

“At this point, completely unprovoked, the accused struck Mr Machnowski to the left side of his face with a knife.

“Mr Machnowski observed a small blade in the hand of the accused. He put his hand to his face and told her to ‘f*** off’.”

But violent Dobbie continued her attack and walked around the back of her victim and slashed him to the back of his neck.

He was standing with his bicycle between his legs and was unable to move away from her before she struck for the second time.

Dobbie ran off to catch up with her boyfriend who had walked on and she was heard laughing.

Mr Machnowski went to hospital to be treated for his injuries and needed a stitch on his face for a one centimetre cut, and six at the back of his head for a 10 centimetre wound.

He has scarring from both injuries.

A media appeal was circulated to track down Dobbie and CCTV from the street showed the attack taking place.

Police were lead to CCTV of the couple getting on a train at Carntyne and were given information Dobbie was “acting erratically and shouting about having slashed someone”.

She was caught after her boyfriend was spoken to by police about an unrelated matter later that month and said he was with Dobbie on the day of the attack.

The court heard Dobbie - who has a previous conviction for assault - was on bail at the time of the attack.

Sheriff Paul Crozier told her: “In the circumstances whilst I obtain reports I do not consider it appropriate your bail should be continued.”

He deferred sentence until later this month.
