Three teenagers have been found guilty of the manslaughter of a young rapper who was stabbed to death in a fight over a stolen bicycle in New Cross.

Myron Yarde, 17, aka Mdot, was backed up against a wall and stabbed five times in the legs on the evening of April 3.

Fauz Richards, 19, known as Mags or Maggie, and two youths aged 15 and 16 were acquitted of murder but found guilty of manslaughter following an Old Bailey trial.

One of the stab wounds sliced through Myron's femoral artery, causing massive bleeding.

The student collapsed near the scene of the attack in Camplin Street and was pronounced dead shortly after arriving at hospital.

Adjourning sentence until January 13, Judge Nicholas Cooke said that "the evil" of knife crime "has to stop, too many young men lose their lives in this way".

Prosecutor Lisa Wilding QC told jurors: "The events in Camplin Street were a brutal culmination of matters that had begun a couple of hours earlier and arose partly from the theft of a bicycle.

"However, that itself reflected an ongoing tension between groups of youths who lived in different but neighbouring parts of New Cross."

Among Myron's friends was promising 16-year-old rapper Leoandro Osemeke, aka Showkey, the court heard.

Leoandro would have been a witness in the case but was himself fatally stabbed in an unrelated incident at a party in Peckham, south-east London, jurors were told.

Myron had lent his bike to Leoandro who had taken it to buy a pizza in the rival Monson neighbourhood where it was snatched, the court was told.

The court heard how Myron was said to have been armed with a machete as he and some friends tried to get a bike back from the rival group, and four of them were lured by the youngest defendant to Camplin Street, where Richards lived.

The 15-year-old defendant was heard to taunt Myron by saying, "What you gonna do? My olders are here now", the court heard.

Myron was cornered by all three defendants who were armed with a flick-knife and two kitchen knives, the court was told, and two of his friends ran off as Myron was backed up against a wall by the three defendants.

According to Myron's remaining friend, who tried to stop the killing, the victim had tried to lash out at Richards before being stabbed.

Jurors also heard accounts from members of the public at the scene.

Ms Wilding said: "It is clear that the events on Camplin Street were fast, terrifying and shocking, both for participants and witnesses.

"Each witness noticed different things and had a different perspective. What is clear is that at the moment he was fatally stabbed, Myron Yarde quite literally had his back against the wall."

Regardless of whether Myron was armed at the time of the attack, he was "effectively helpless", Ms Wilding said.

On hearing on Snapchat that Myron had been seriously injured, the 15-year-old defendant allegedly said: "Why the F did he have to come to Monson? I think I've killed him."

A red and white kitchen knife found in Richards' back garden had Myron's blood on it, the court heard.

When the 15-year-old was arrested four days later, he told officers: "Some people deserve to die, I just mean not everyone is innocent, including that boy that died."

The defendants all denied murder and were found not guilty but then found guilty of manslaughter. The 15-year-old told jurors that he stabbed Myron once in self defence, causing the fatal wound, while Richards knifed him four times.

Richards told jurors he was not at the scene and a witness was mistaken. The 16-year-old defendant did not give evidence.

The machete Myron was said to have had on him was not found at the scene.

Charlotte Edmonds, 32, and Jamie Kennedy, 31, of New Cross, were convicted of perverting the course of justice.
