It comes after a man in his thirties was knifed to death in a “street battle” on Tuesday night, becoming London’s fifth murder victim in six days.

Scotland Yard have launched 61 murder investigations already this year, with 37 of them fatal stabbings.

In the video in West Norwood, a thug can be seen sprinting after the moped rider wielding a huge knife.

The filming motorists scream in horror as the distressed passenger shouts to the moped driver: “Drive away! No! No! No! Do you want to die! Look at the big knife! Oh my god! The big chopper that the man…the little boy's got you know!”

She tells the driver to follow the thug and they drive towards a roundabout.

The passenger then says: “This guy's got a deathwish bruv! Do you see the big f***ing knife in his hand!”

The car catches up with the moped rider who incredibly stops his vehicle to gesture at the knife-wielding teen.

The passenger yells at the motorcyclist to speed away from the thug shouting: “Are you all right? Drive! Drive off! No seriously drive! Who wants to get stabbed up?”

The moped driver pulls away just as the teen manages to catch up with him.

LAWLESS LONDON

In another clip, filmed on a nearby road, the women have parked their car and found the moped driver.

He is now filming the thug, who has been joined by a pal, on his phone as they chase him down the street.

Again, he drives off just as they get close.

The thug screams after him: “F*** off p***yhole!”

Sun Online have contacted the Metropolitan Police about the incident.

It comes after a man died following a triple stabbing in Barnet in what was the fifth killing in the capital in just six days.

The suspected murder came after a man in his 40s was stabbed to death in Stratford in the early hours of Monday.

That killing followed three homicides in the space of 24 hours, including two teens who were fatally attacked at teatime on Friday.

Cheyon Evans, 18, was found stabbed in Tooting, south-west London, at 4.42pm, and died at the scene.

Just 12 minutes later Eniola Aluko, 19, from Thamesmead, south-east London, was shot dead in a car park in Plumstead.

On Saturday, a man in his 30s was stabbed to death in a field next to a nursery and a mosque in Alton Street, in Tower Hamlets, east London, just before 2pm.

As well as the violent deaths, another victim, 45, was left in a critical condition when he was stabbed in Enfield at about 3.30pm on Saturday.

A 17-year-old boy was also left fighting for his life after he was shot on the Tulse Hill Estate, south west London, at around 9.40pm on Sunday.

Violent crimes have soared in London since Sadiq Khan took over as mayor, with 2018 the bloodiest year in almost a decade.

Figures last month revealed five young people are attacked with a knife every day in London and Mr Khan warned it could take a "decade" to turn back the tide of violent crime.

However Met Police chief Cressida Dick recently hailed a reduction in stabbings of under-25s after more stop and searches.
