A 14-year-old boy was knocked off a moped and killed by a rival gang in a "violent and frenzied" knife attack, a court heard.

Jaden Moodie had allegedly been dealing drugs for a London gang when he was targeted by the group on the evening of January 8, the Old Bailey was told.

Ayoub Majdouline, 19, was allegedly one of five young men who had driven around the area in a stolen Mercedes looking for someone to attack.

Prosecutor Oliver Glasgow QC told jurors how they had armed themselves with knives and gone to "great lengths" to hide their faces and cover their hands.

He said: "On finding Jaden Moodie, the Mercedes drove straight towards the moped, swerving onto the same side of the road so that it struck Jaden Moodie head on."

Members of Jaden's family gasped and wept as jurors were shown "harrowing" CCTV of the attack.

Mr Glasgow said: "14 seconds was all it took - Jaden did not stand a chance."

He told jurors Jaden could do nothing to avoid the impact and his crash helmet came off as he was "catapulted" over the bonnet.

Three young men then got out of the car and stabbed Jaden as he lay "defenceless and seriously injured" on the ground.

Mr Glasgow said: "Rather than help him, the three males embarked upon a violent and frenzied attack, repeatedly stabbing him with knives that they must have armed themselves with for the purpose of attacking him."

The prosecutor said the CCTV demonstrated Jaden's killers had "no qualms about playing out their petty rivalries using the blade of a knife".

Jaden suffered nine stab wounds and bled to death in the road as the attackers ran back to the car and sped off, the court heard.

The Mercedes was left in a quiet cul-de-sac and the occupants "calmly walked away as if nothing happened", jurors heard.

As the killers left the area, they threw away a knife and a pair of yellow rubber gloves which was recovered from a drain the next day, the court heard.

Mr Glasgow said Jaden's blood was found on the knife and traces of the defendant's DNA on the handle.

The victim's blood was also allegedly identified on one of the gloves, with the defendant's DNA inside.

Burnt clothes matching those of the killers were later found in a churchyard, it was claimed.

The defendant, from London, disputes playing any part in the attack, the court heard. He denies Jaden's murder and possession of a knife.
