Shocking video: A girl gets badly beaten by her peers

This socking footage shows a 14-year-old girl getting severely beaten by at least five other girls after they lured her to a sleepover.

Naomi Johnson is punched repeatedly in the head, dragged by her hair and stamped on, while struggling to get away.

The vicious bullies later posted the attack on Twitter trying to ridicule their victim even further.
