Sickening video shows vicious assault on schoolgirl in locked hall

A sickening video has emerged of a gang of bullies laughing as a schoolgirl, 12, punches and kicks a fellow pupil after reportedly locking her in the sports hall.
The disturbing film shows a blonde girl grabbing another pupil's hair before repeatedly punching her in the head and face at Fraserburgh Academy, Aberdeenshire.
The thug tried to yank her victim off her seat on a bench in the sports hall using only her hair. Two young girls pleaded with the bully to stop. One said: 'That's not on.'
But the bully continued her assault, shouting 'Get off your seat or I'll do worse.'
The blonde then began frantically kicking her in the head, face and torso while shouting: 'You f****** silly cow.'
At one point, the girl behind the camera laughs and says 'Nice' as the bully smacks her victim in the head.
The sound of each punch can be heard echoing through the hall, which the bully reportedly locked before starting the attack.
The visibly distressed brunette's hands and feet can be seen physically shaking as she cried, pleading with the young girl to stop.
But the pupil didn't seem deterred by this and continued to use both fists to punch her victim for another minute.
The footage was posted on Twitter yesterday, with the caption: 'F******disgusting. Locked a girl in the PE hall and battered her.'
It has already attracted more than 700 retweets, 1,500 likes and dozens of comments from disgusted viewers.
One Twitter user said: 'Actual wee tramps. Imagine sitting videoing that and laughing.'
Another said: 'Wee lassie and her pals thinking they're big.' And one added: 'Makes me feel physically sick.'
Police revealed that the attacker in the video is just 12 years old.
A spokesman said: 'Police Scotland can confirm that a 12-year-old girl has been charged in connection with an alleged assault in the Fraserburgh area on Tuesday May 23, 2017.
'She will be reported to the Youth Justice Management Unit (YJMU).'
A spokesman for Aberdeenshire Council said they would not be commenting while the police investigation is live.
According to the YJMU, youth justice practitioners, working in private and without a jury, will take a 'welfare focused approach' to the case which 'aims to address the causes of behaviour to prevent further criminal offences'.
Staff are likely to liaise with the school and social workers to try to determine the cause of offending behaviour.
