A 17-year-old boy was shot in the head and stabbed with a machete as he lay defenceless on the ground outside a music studio.

Tyler McDermott was killed in Tottenham on April 13 last year.

After a three-month trial, Tyrese Barnett, 20, Leo Reid, 20, Rhys Antwi, 20, and Kalam Bagge, 19, have all been found guilty of Tyler's murder.

Prosecutor John Price KC previously told the court "tension and hostility” had been brewing between two groups of young people in the studio that morning.

Mr Price said that Barnett shot Tyler in the head with a ball bearing then Reid stabbed him with a machete.

Despite the efforts of paramedics, Tyler died in hospital the following day.

The two attackers were identified by police and found two days later sitting together at Heathrow Airport with one-way tickets to Jamaica, the court heard.

The CCTV footage showed the gun was fired twice, with the second shot fired at Tyler’s friend, Kamali Lindo, the prosecutor said.

The prosecution did not allege Reid caused Tyler’s death with the machete, but it did help prove he shared guilt for the murder, the court heard.

Barnett, of no fixed address, Reid, of Tulse Hill; Antwi, of Prentis Road in Streatham; and Bagge, of Nimrod Road in Tooting, will be sentenced on September 20.

Barnett was further found guilty of attempted murder while Reid and Antwi pleaded guilty to possession of an offensive weapon ahead of the trial.

Two other men were charged with murder but were acquitted by the jury on Wednesday (June 19) - Coker, 21, of Bowen Drive in Sydenham, and McBeth, 20, of The Glade in Croydon.
