A knife fight was played out at school home time just off Thornton Heath High Street as horrified parents collected their children.

The running battle captured on a car’s dash cam shows four rival gang members  stabbing at each other at 4.20pm on Friday on June 7, on Grange Road, leaving at least one teenager with knife wounds.

We can reveal that police have now  made three arrests in connection with the incident.

The footage  of the brawl went viral and was featured in the national press. It  shows two of the males on a moped pull up next to a Peugeot — then one of them, wearing a helmet, pulls  open its door and repeatedly hacked at one of the two occupants with a flick knife.

The Peugeot’s driver and passenger, who were both armed with knives, then leapt from the car. 

The driver chased one moped thug while brandishing a kitchen knife — while the passenger and helmeted moped attacker squared off in the street.

The Chronicle has also been shown a second video which shows the build up to the knife brawl which was reposted from Facebook. 

It shows the driver of the Peugeot and the moment the car’s windscreen is smashed after first confronting a  man who is walking on the opposite side of the road to Whitehorse Manor School who he calls a ’snitch’. 

The car can then be seen driving away from Grange Road on to the High Street after the incident and the driver who is commentating shows his slashed blooded hand and talks about gang stuff.

The 17-year-old victim was  taken to hospital where he was treated for stab wounds. The Air Ambulance landed in Grangewood Park. The victims injuries were not life-threatening.

Witnesses described how three of them had knives and that one of the guys on the moped had a flick knife which he dropped it because he was stabbing so ferociously with it. 

Another said:   “The guy on the moped stopped in front of me and just started attacking the car.”

Others over heard the word ‘bore him up’ being used which is street slang for stabbing.

A police spokesman told The Chronicle that three people have been charged with a number of offences, including; GBH, affray and the possession of pointed and bladed article in a public place.

The spokesman continued: “They have been remanded in court and await trial. Further enquiries will continue.”
