THIS is the shocking moment a group of "feral" thugs attack each other with machetes and hammers before armed cops arrive.
The unnerving brawl took place just meters from a primary school when six masked figures began to punch each other as passers-by ran for their lives.
Terrifying video footage taken outside Southern Road primary school in Newham at around 3pm yesterday captures the nightmare as it unfolds.
In the clip the group throw punches before smacking each other with what appears to be hammers and machetes.
Moments later an unmarked car speeds into the shot and two police officers race out, wielding machine guns to break up the fight.
Four teenagers were arrested at the scene and one was taken to hospital with injuries, the police have said.
