A 13-year-old schoolgirl was savagely attacked by two other girls in distressing footage posted online.
The victim is grabbed by her hair, thrown to the floor and repeatedly kicked and punched.
She then hits the path before rolling onto a grassy verge.
The victim tries in vain to get up back up but as onlookers goad and cheer, her attackers punch her back to the ground.
One boy tries to pull one of the attackers off of the teenage girl before a male voice can be heard saying “hey big man, stop touching”.
Another says: “Get the f*** off them.”
One of the attackers can also be heard telling the victim to “get the f*** down, yeah”, as the 13-year-old yells: “Get the f*** off me.”
The teenager tries to get up a second time when one girl, who joined in once she was already on the floor, punches her one last time in the face before walking off.
The allegedly unprovoked attack happened in Essex on March 23.
The victim's mum said the girls who assaulted her daughter had done it before and have threatened other people on social media.
She said: “These girls had a problem with another group of girls and they just jumped my daughter.
