A schoolgirl bully stamps on a crying classmate's head in an alleged row over a boy in this shocking footage.
A teenage boy filmed the violent assault which shows a girl, wearing a red coat and glasses, hitting the blonde child and throwing her to the ground.
Another schoolgirl then joined in the attack , appearing to bend over the victim to intimidate her.
Both of the attackers punch the girl as she sits on the ground putting up no resistance in front of a small crowd of teens.
They can be heard quizzing the girl about her relationship with a boy.
The attackers, thought to be between 13 and 15 years old, took turns to hit and humiliate the victim as the cameraman offered a running commentary.
The attack was filmed in Yelets, western Russia
She eventually manages to get to her feet but the girl in the red coat forces her back down on her knees and then kicks her in the face and the back of the head, before stamping on it.
The video ends with the attackers warning their victim she will be beaten up even worse if she tells anybody about what has happened.
However, the attack quickly became public knowledge after the footage was posted on social media.
Police launched an investigation and have already spoken to all of the girls involved.
The victim has been checked over by doctors and did not suffer any serious injuries, but she is still said to be in shock.
