A teenager murdered a 16-year-old boy over a mobile phone. Stelios Averkiou was sitting on a park bench with two friends when he was targeted in broad daylight by Kyi-Riece Sylvester, in Lordship Recreation Park in Tottenham, north London, on August 1, 2021. Sylvester, 18, stabbed him in the thigh and ran off with his mobile phone, the Old Bailey heard. His associate, Leon Gruber, also 18, had made off on a bicycle belonging to one of Stelios’ friends, jurors were told.
Jacob Hallam KC had said: “The prosecution say both defendants acted as a team to rob those they came across. In the park, on August 1, they decided to rob Stelios Averkiou and those he was with.
“When they met with resistance from Stelios Averkiou, Sylvester stabbed him a number of times.”
Emergency services attended the scene but were unable to save him as the injury was “so severe that it cause him massive blood loss”.
Mr Hallem added: “He fell into unconsciousness from which he never surfaced, and died in hospital on August 10.”
A post-mortem examination found the 16-year-old died from blood loss after sustaining three stab wounds to the upper thigh, with one 16.5cm deep.
Mr Hallam had told jurors there it was not in question that the defendants robbed Stelios of his mobile phone and his friend’s bicycle or that Sylvester stabbed him.
He said issues included if Sylvester meant to cause really serious harm and whether Gruber intentionally encouraged him.
Gruber, of Edmonton, north London, and Sylvester, of Cheshunt, Hertfordshire, denied murder and an alternative offence of manslaughter.
On Tuesday, Sylvester was found guilty of murder and Gruber was acquitted of both charges.
Sentencing was adjourned to a date to be fixed.
