Two teenage boys have been found guilty of killing a market trader in a row over a stolen watch.

Rashid Naeem was knifed in the chest during a struggle near his stall in Queen's Market in Green Street, east London.

Following a trial at the Old Bailey, Karlton Burton, 15, who was responsible for delivering the fatal wound, was yesterday found guilty of murder.

His friend, Javauntee Campbell, 16, who landed a punch on the victim, was cleared of murder but convicted of manslaughter today by a majority of 10-1.

Both boys can now be named, after the trial judge decided it would be in the public interest to lift a court order banning their identification due to their age.

A third defendant, aged 15, was cleared of murder. He cannot be named.

Campbell was remanded in custody ahead of his sentencing along with Burton on a date to be fixed in September.

Mr Naeem's family, who were in court throughout the trial, wiped away tears as the final verdict was delivered.

The judge, Richard Hone QC, thanked the jury for their careful consideration of the case, adding: "It is devastating how people aged 15 and 16 go out with knives and cause such terrible consequences."

Turning to Mr Naeem's relatives, the judge offered his condolences and said he hoped the trial would now bring some closure.

The court heard how Mr Naeem and his brother were working on the stall which sells mobile phones and watches on the afternoon of Sunday, February 16.

At around 2.40pm, the three boys went to the stall and "started fiddling around with some of the objects", prosecutor Sean Larkin QC said.

Campbell took a watch from the stall and they walked off, before returning within a few minutes to a neighbouring stall.

Footage caught on CCTV showed that as the two brothers approach the defendants, Burton reached down to his ankle and got out a knife, concealing it in his jacket.

He said: "The two brothers are unarmed and they go over and ask for the watch back and there is a struggle, in the course of which...the deceased is stabbed in the chest."

Campbell told the court he went to pull Burton off and landed a punch on the market trader's arm in the process.

The three defendants ran away but were spotted nearby around an hour later by emergency services attending the incident.

The murder weapon has never been recovered, the jury was told.

Later, the boys met up again at Campbell's house where the 16-year-old said he confronted Burton about what had happened.

While giving evidence in his defence, Campbell said: "I asked him did you poke the guy? He said 'no I don't think so, it did not go in'."

He said he became "angry", adding: "I called him stupid and I told him why. I was shocked."

The jury was told Burton, who has been diagnosed with Attention Deficit Hyperactivity Disorder, did not dispute being responsible for stabbing Mr Naeem but was claiming lawful self defence.

The prosecution said the boys, from east London, were part of a "joint enterprise" and provided "strength in numbers".

However, the jury decided that the other 15-year-old defendant was not responsible for the killing and Campbell was guilty of manslaughter, but not murder.

Campbell's mother, who had been in court throughout, wept uncontrollably at the verdict was delivered.

All three defendants had denied murder.
