A group of teenagers accused of stabbing a 19-year-old to death in South Harrow dropped a rubber glove in a minicab as they made their getaway, a court has heard.
Two 14-year-olds and a 16-year-old, who cannot be named for legal reasons, deny murder, wounding with intent, attempted wounding with intent and conspiracy to cause grievous bodily harm.
The defendants allegedly took a minicab from an estate in Hendon to Harrow and made the driver wait as they murdered Hussein Ahmed, it has been claimed.
Mr Ahmed was stabbed once in the back outside the Kababish takeaway, in Northolt Road, near South Harrow tube station, on Friday November 18.
The victim had been riding his bike when he suffered massive blood loss from the knife attack and fought for his life for days in hospital, but was pronounced dead on Wednesday November 23 after his life support was withdrawn .
Another boy was stabbed in the arm and stomach, while a third narrowly avoided injury as an attacker slashed the sleeve of his jacket.
During the trial, it was alleged the group returned to the waiting cab, seven or eight minutes after the attack, and told the driver "Drive, boss".
The Old Bailey heard how two of Mr Hussein's alleged attackers were captured on CCTV wearing purple plastic surgical gloves.
Giving evidence from behind a screen and with help from an interpreter, Saifuddin Jaji told jurors how he picked up four youths in his white Toyota Prius on the afternoon of November 18 last year.
The teens played loud music during the journey, both to and from Harrow, until Mr Jaji told them he had a headache and asked them to turn it off.
Describing their mood in the car at they returned to the Grahame Park Estate, Mr Jaji said: "When they turned off the music they were talking to each other. They were looking very worried."
The court heard how the driver asked for £18 up front to take the fare, and then demanded £24 for the return journey - but the boys were £1 short.
Prosecutor Anthony Orchard QC asked: "When you do a drop off do you check your car?"
The witness replied: "I checked and saw a glove was on the ground in the front side so I took it. It was a rubber glove.
"I threw it away - I did not suspect anything."
The Embassy Cars driver told jurors he made a U-turn after dropping the boys off and took on two more fares that day.
When police contacted him the same evening, Mr Jaji said they told him "these boys stabbed someone", but before then he had no suspicions that anything was wrong.
The boys, who cannot be named because of their ages, deny the charges.
A fourth alleged attacker aged 16 fled the country and is wanted by police, the court heard.
The trial continues.
