VIDEO: Vile bully batters schoolgirl, 13, as classmates laugh

SHOCKING footage has emerged of a bully savagely attacking a defenceless girl while her classmates laugh.

The disturbing video shows the teen viciously pummelling a vulnerable girl.

She then kicks her in the stomach while she is lying on the floor, before yanking her hair back.

A group of teenagers surround the attack and giggling can be heard throughout.

SICKENING: The footage shows a teenage girl getting punched and kicked while on the floor

One child can be heard saying: “Oh my God.”

But no help is offered until one lad out of shot of the camera shouts: “Break it up. Break it up.”

The sickening clip was taken at the entrance to Gleniffer High School, in Paisley, during a lunch break on Tuesday.

It was shared on social media sites by pupils.

The mother of the young victim said last night: “My daughter didn’t want to fight that other girl, but she was attacked anyway.

“She is sore and bruised from the attack but that fact that it was filmed has made it worse.”

The attack was reported to police and education chiefs, who have promised to take action.

VIRAL: The girl is repeatedly punched

A Renfrewshire Council spokesman said: “The behaviour shown in the video is completely unacceptable.

“We are cooperating with a police investigation and can confirm that the young person allegedly involved in the assault is currently not in school.

“We are also carrying out our own disciplinary investigation.”
