olice have arrested three people amid chaotic scenes near a funfair at a south London common after a “number of incidents of violence” and reports of a stabbing.
Officers swooped to Blackheath Common on Tuesday evening to a number of assaults and a reported stabbing.
No victim for the stabbing was found, said the Met.
A police spokesperson said: “Police are dealing with reports of antisocial behaviour and a number of assaults at Greenwich Park.
“A stabbing has also been reported; no victim has been found.”
They added: “Three people have been arrested for possession of an offensive weapon and related offences.”
Officers have put in place a Section 60 order until 5pm Wednesday which gives officers extra search powers.
A witness Sean Ash, who had driven to the Common to take his children to the funfair, said there were hundreds of children on the green space and scenes of disorder.
“When I arrived, we saw a police van, and there was hundreds of young people, all aged about fifteen, sixteen,” he told The Standard.
“My son was in the back seat, and he said, ‘They’re hitting the police’. A police chopper came over the top, they’re still there now.”
The leader of Greenwich Council said he was aware of the disorder and issued an “urgent appeal” to parents in the borough to make contact with their kids if they did not know where they were.
“If your child is in the #blackheath area – or you don’t know where they are – please make urgent contact. Make sure they go home asap,” said Dan Thorpe.
The area’s MP, Matthew Pennycook, also urged locals to avoid the area.
“The police are deploying extra resource,” he said. “Please avoid the area. If you believe your child is at the funfair or in the area, please ask them to return home immediately.”
Council officials said the funfair had now been closed “due to incidents of disorder.”
