A girl is dragged to the floor and kicked in the head by a group of youngsters who are still in their school uniform in a vicious attack.
The petrified youngster screams as she is pushed to the ground and a boy she is with tries to protect her from numerous blows.
She is dragged to the floor, kicked in the head and pulled by her hair by the savages as they both plead for the attack to stop.
It is believed the footage was shot yesterday in Central Park, Dartford, Kent, and it has since been shared hundreds of times online.
The woman who posted the video, Nicola Parfitt, described it as an "unproved attack" against the girlfriend of her son's friend.
Her post read: "F ** king fuming that there are scum out there, that even video this s**t for fun.
"My son out in park yesterday his friend's girlfriend gets attacked for no reason.
"So glad my son jumped in don't even know why they are causing trouble.
"Hope there parents are proud and ya know what ya kids are up to (sic).
"Share this everywhere.
"In uniforms as well, shameful."
A second video later emerged showing the same assault.
One Facebook response from Alvin Mulindwa read: "Absolutely heartbreaking disgusting behaviour. So sorry for the victims.
"I hope the police deal with the all of the attackers including the people filming."
Tracey Apps added: "Police need to be involved this is assault - poor girl - savages!
"I find this disgusting. I'd be so ashamed if I was the parent of one of those horrors."
Kent Police has been contacted for comment.
