Smiling teenage killers jailed for life for machete attack on 14-year-old Kelyan Bokassa on London bus

The 16-year-olds smiled as they attacked Kelyan Bokassa on the top deck of a 472 bus. He was stabbed 27 times while trying to defend himself with his school bag.

As he lay dying he called out “I want my mum,” the Old Bailey heard.

Judge Mark Lucraft KC detained them at His Majesty's pleasure for life.

He told the pair they would be locked up for a least 15 years and 10 months before being eligible for parole.

Judge Lucraft said Kenyan's death was a "senseless loss" of yet another young life to the "horrors of knife crime".

CCTV footage showed Kelyan went to sit on the back seat on the top deck, with a knife in the waistband of his trousers.

Ms Heer said the teenager looked around and out of the windows before taking his seat "giving every impression that he was concerned for his safety".

The defendants, who cannot be named, boarded the bus 20 minutes later each armed with identical machetes hidden in their clothes.

The pair walked towards Kelyan "with purpose" and withdrew their blades before immediately stabbing him without uttering a word to their victim.

Ms Heer said: "Since Kelyan Bokassa was seated on the back seat, he was cornered, unable to escape as the defendants repeatedly thrust their knives towards him, smiling as they did so."

The attack lasted around 14 seconds, with the youths thrusting the machetes towards Kelyan 27 times.

Ms Heer went on: "Kelyan Bokassa had no time to reach for his own knife, which remained in his trousers, and instead tried in vain to protect himself with his school bag.

"There were several other passengers on the top deck who fled in panic when they realised what was happening. They describe hearing intense screaming from the back of the bus and the victim shouting, 'Help. Help. I've been stabbed'.

"They describe both defendants making quick, forceful movements towards Kelyan Bokassa as he tried to defend himself."

The bus driver activated his emergency alarm just before 2.27pm and the defendants fled when the vehicle stopped at Woolwich Ferry.

Kelyan stumbled down the aisle to the stairs, where another passenger went to help him.

The boy was heard to say: "Take me to my mum's. I want my mum," before his legs buckled, bleeding heavily from a wound to the leg.

Members of the public flagged down a passing police car and officers found Kelyan had collapsed and his body was limp.

Despite attempts to save him, Kelyan died at the scene at 3.23pm.

One of the machetes was thrown into the River Thames, but was later recovered by police.

The defendants were quickly identified from CCTV on the bus and arrested.

In a victim impact statement, Kelyan's mother Marie Bokassa said: "At least my son is at peace, and those two kids are going to have a really tough time.

"I ask myself what has happened to those two boys that has resulted in that terrible act of violence, and I cannot imagine how can they be so angry.

"What they did was horrific and I do not know what has led them to do this, and maybe I will never."

She told the court her son had loved food, cooking and football, and brought her flowers on her birthday.

Speaking through tears and wearing black, she said: "He would put music on and we'd dance together in the living room.

"He loved Mr Bean, which we watched together, and he would laugh. I miss his laugh, miss his voice.

"I will never see his children or be a grandmother and he will never have his own family."

Ms Bokassa added that she had spent her son's 15th birthday at his graveside.

During the sentencing hearing, members of the public sobbed loudly and hid their faces as footage of the attack on Kelyan was shown in court.

The defendants gave no visible reaction in the dock.

The court heard both defendants have previous convictions for carrying blades in public.
