A mother whose son was punched and kicked by a bully has urged people to watch the 'disgusting' attack, which was filmed on a mobile phone.
The woman said she wanted the 56-second clip in the public domain to help raise awareness of the levels of bullying going on in Britain.
In the footage, shot near the boy's home in Nuneaton, Warwickshire, the bully shouts at the victim: 'Get down here', swears at him and asks him 'Are you f****** mad?'
The boy, wearing a hoodie and a backpack, is clearly terrified as the chubby attacker lands several punches, knocking him to the ground and then stamping on his head.
The victim's mother told the Coventry Evening Telegraph: 'It is disgusting, my son wouldn't hurt a fly, yet why would someone do this to anyone.
'I was sent it via friends and family, but it is unacceptable. You can see in the video he didn't retaliate, or come back at him.'
She said: 'My son has been bullied and threatened in the past, but never been physically attacked.'
The boy managed to shield himself with his backpack and fortunately did not suffer serious injury.
'It could have been a lot worse,' said his mother.
She said: 'To the children who are bullied, I think it's important to know that the bully is the one in the wrong.
'It's never acceptable to treat people like they're less than you or unworthy just because you're not the same. They are somebody else's world and they're loved by many people for who they are whether you like them or not.'
