A teenage rapper has been sent to prison for killing a gang rival at Brent Cross Shopping Centre.

Bhoniefas Rexson, 19, stabbed 21-year-old Gedeon Ngwendema in the chest on May 4 last year.

The “committed” gang member, who appeared in four YouTube music videos, had admitted manslaughter and possession of a knife.

On Wednesday, he was jailed at the Old Bailey for 14 years with a further four years on extended licence.

Rexson had previous convictions for robbery and having a lock-knife and Rambo-style blade, the court was told.

At the time of the killing, he was also on police bail on suspicion of murder, the court was told.

Judge Anthony Leonard QC said the “appalling” violence in front of adults and children at Brent Cross came after Rexson told a friend at Wormwood Scrubs prison he was looking for a knife “for the ride”.

The teenager searched the internet for a shop selling knives and, less than 35 minutes later, had one tucked into his tracksuit bottoms in the busy shopping centre.

The Thugs For Life gang member came across the victim, who was associated with the rival A9 gang, outside a JD Sports shop “by chance”.

During a brief confrontation, Mr Ngwendema was stabbed in the chest, with the blade piercing his heart.

He stumbled towards Marks and Spencer and collapsed on the concourse where he died.

He was heard by shoppers to say: “I’ve been duked (stabbed). Someone get me an ambulance.”
