The family of a schoolgirl who was filmed punching and taunting a boy have gone into hiding after the video swept the internet.

The shocking film is believed to show the 11-year-old girl abusing a classmate, aged 12.

The images, reportedly filmed by a pupil, were shot outside a high school in Lanarkshire, which has suspended the girl.

The two-minute clip shows the girl allegedly squaring up to the boy, while her friend filming it shouts: "I need to get home. If you're going to hit the boy, hit him."

She then allegedly punches him FIVE times in the face. The boy - 2ft taller than his alleged tormenter - doesn't react and tells her bravely he doesn't hit girls. As he tries to walk away she blocks his path before allegedly hitting him again.

Now the stepdad of the girl said they have been forced to go into hiding because of threats by online viewers of the footage.

He told the Scottish Sun: "There are a lot of threats because it went viral. It's not spilled into violence yet. But it's not safe with what's gone on.

"She knows she's done wrong. She can't defend it.

"She's been told to stay away from school today but she won't be going back."

Within hours of the film going on YouTube it caused a storm of protest. It was later removed, but not before several hate sites were set up. But relatives of the boy were more reasonable.

One said: "We have got to remember that this is involving young children."

Another family member added: "He said he's fine. He doesn't want anything done about it. He said she does this to everyone. She is a bully."

A North Lanarkshire Council spokesman said last night: "A full school investigation will be carried out and action will be taken. Bullying of any kind is not tolerated."

Police last night said two girls aged 11 and 15 were the subject of a report to the Children's Reporter.
