A teenage boy was fatally stabbed on a bus home from school in Chadwell Heath in a “revenge” attack after he posted a drill music track online, a court has been told.

Former Romford Boxing Club member Tyler Hurley, 16, was allegedly knifed by Carlton Tanueh, 19, on the 173 service – just 20 minutes after the Year 11 pupil left The Warren School.

CCTV footage played at Southwark Crown Court on Thursday (December 1) captured the alleged attack in front of passengers, including parents with prams, on the afternoon of March 14 this year.

Prosecutor Caroline Carberry KC told jurors the “fear on his face is obvious” as “unarmed and totally vulnerable” Tyler, who was wearing his school uniform, suffered “unsurvivable” injuries.

He was taken to hospital but died in the early hours the following day.

Tyler had three weeks earlier “caused upset to some very dangerous young men” by uploading a drill music track to YouTube, the court heard.

Ms Carberry said the lyrics mocked, “in pretty vile terms”, Tanueh’s associates, in particular one member of the group who was stabbed, though not fatally.

And, following an unsuccessful armed attack just over two weeks before the fatal stabbing, Tyler “taunted the group” after he managed to escape unhurt, she told jurors.

“He was murdered, the prosecution say, in cold blood, intentionally and without emotion by this defendant,” she said.

“This defendant’s behaviour was an act of rage and, as you will hear, revenge, and Tyler Hurley’s young life was deliberately – brutally – cut short because of petty grievances, because this defendant chose to arm himself with a deadly knife and because he chose to attack Tyler Hurley with it in the middle of a Monday afternoon as he made his way home from school.”

The court heard Tanueh, who was “out of his own area” and “looking for trouble”, thrust a zombie knife twice at Tyler’s body, inflicting a fatal wound through his arm and armpit.

Tanueh, of no fixed address, denies murder but admits two counts of having a knife in a public place, the jury was told.

The trial continues.
