A teenager who stabbed his friend to death at a birthday party before going on the run in Kent has been locked up.

Munashe Charles Kutyauripo, known as Charlie, 16, collapsed and died outside a party venue in east London on January 9 last year after being knifed in the chest in a row over a tracksuit.

In the aftermath, his attacker Aaron Gaiete, 17, fled London but was found by Kent Police officers around three weeks later lying low in Margate.

He was transferred to London and charged with Charlie's murder on February 2.

He was found guilty of murder at the Old Bailey last week following a retrial. He returned there today, when he was handed an indefinite sentence with a minimum term of 14 years.

The fatal attack, which lasted just two seconds, was was captured on CCTV and witnessed by several young party-goers who had been at the sports centre in Woodford.

In the footage, the defendant suddenly spun round and lunged towards Charlie, stabbing him once in the heart and once in the shoulder with a kitchen knife.

Charlie staggered back towards the party, chased by the defendant who was still brandishing the knife. Once Charlie had collapsed outside, Gaiete ran off through Woodford and went to a friend's house 10 minutes from the scene.

Charlie was taken to Whipps Cross Hospital, but died an hour later.

"In two seconds that night, a night that should have been full of celebration, Charlie's life and future were taken from him and his family" - DI Jamie Stevenson

A post-mortem examination showed he had been stabbed twice with a 6in blade, with the fatal wound struck with severe force into his heart.

A kitchen knife was found by police discarded near the scene with Charlie's blood on it and the defendant's DNA on the handle.

The two boys, who had previously attended the same school, had been good friends but had fallen out towards the end of 2015.

On the night of the stabbing, Gaiete said he armed himself because he was expecting gang members to be at the party, even though it was an invite-only, no-alcohol event with parents manning the doors.

He claimed he acted in self-defence, although no knife was found on Charlie's body.

After Gaiete was convicted, Detective Inspector Jamie Stevenson, from the Met Police Homicide and Major Crime Command, said: "In two seconds that night, a night that should have been full of celebration, Charlie's life and future were taken from him and his family.

"They have been devastated by his murder, and have showed tremendous courage throughout this investigation and the prosecution case.

"The defendant made a number of choices that night, which have resulted in the guilty verdict. He chose to go to the party that night and he chose to go armed with a large kitchen knife. That shows he was looking for, or expecting trouble, and if and when that trouble came he would use his knife.

"At 17 years old he is now a convicted murderer, who has shown no remorse for taking Charlie's life.

"He immediately went on the run to try and evade the police and still to date has not admitted murdering Charlie or explained why. In fact he has tried to blame Charlie, claiming he acted in self defence."
