A teenage killer attacked his elder brother in the dock after he helped condemn him to life in jail for stabbing to death Gokhan Durmus, a Turkish youth footballer.

Turrell Auguste, 19, went berserk at the Old Bailey moments after a jury found him guilty of knifing Gokhan Durmus in the neck during a botched drug deal.

His brother Mathais, 21, also stood trial for the murder, but was dramatically acquitted after turning on his sibling in the witness box.

The brothers blamed each other for the fatal stabbing, both claiming not to be the one who inflicted the knife wound.

As the verdicts were delivered, Turrell Auguste whispered: “How can you do this to me?” at his sobbing brother, before lunging at him across the dock.

A dozen security guards took nearly five minutes to restrain the killer as he was wrestled to the ground screaming: ‘I’m innocent’ before he could get to Mathais who cowered in the corner.

Members of the jury were left visibly shaken with several in tears after witnessing the scene, and had to leave the court.

The brothers were together on February 7 when they met Mr Durmus, 22, a promising footballer who had been called up to represent Turkey’s under 15s team.

Mr Durmus’ best friend witnessed the stabbing, in Chatham Place, off Morning Lane, but was unable to say which of the two brothers wielded the knife.

“It was a pre-arranged meeting and in all probability it was drugs related,” said prosecutor Brian O’Neill QC.

Mr Durmus, the eldest of three brothers, who lived with his parents in Walthamstow, managed to get to hospital after the stabbing.

He was in a coma for nine days, but despite undergoing emergency surgery his life support machine was switched off.

The brothers were caught on tape in the back of a police van after their arrests discussing the case against them.

Mathais was heard worrying that he had blood on the sleeve of his jacket, while Turrell could be heard criticising the quality of the CCTV footage he had been shown by detectives.

Turrell Auguste, of Catesby House, Frampton Park Road, Hackney, and Mathais Auguste, of Amberley Road, Leyton, both denied murder. Mathais Auguste was cleared of both murder and the alternative count of manslaughter.

Sentencing was set to take place tomorrow.
