Six people have been arrested after dozens of police officers broke up a large fight involving "around 100" youngsters on Hampstead Heath.
Officers were called to a report of fighting on Parliament Hill in the north London Park on Tuesday evening.
Scotland Yard have warned people to avoid the area and issued a dispersal order after the fighting began.
There are no reports of any injuries, a spokesman for the force said.
Not sure what this is about - but pretty big fight in the park involving hundreds of kids.
