This is the horrifying moment two teenage killers use Rambo knives to stab a defenceless 18-year-old to death on a busy London street.
William Haines, 18, and a 17-year-old youth are filmed plunging the blades into Yusuf Mohamed’s heart and leg at a food shop in Shepherd’s Bush.
CCTV footage shows the knife-wielding thugs move in on Mr Mohamed as he walks past the store on Uxbridge Road.

Haines crosses the road with one of the huge weapons before he thrusts at Mr Mohamed and pierces his heart.
The victim tries to run into the shop but trips by the door and sprawls out on the floor.
The 17-year-old attacker follows up with another massive knife and runs into the store after Mr Mohammed, who crawls backwards with the help of a customer.

Footage shows the pair fist bumping in an alley after the horrific killing.
Haines was found guilty of murder and possession of a blade following a trial at the Old Bailey, while the 17-year-old, who cannot be named due to his age, was found guilty of manslaughter and having a knife.
The pair will be sentenced next month for the attack on June 26 and are expected to be jailed for life.

Mr Mohamed had been walking on Uxbridge road with friends when he was targeted ‘for no obvious reason’, the court heard.
Prosecutor Bill Emlyn Jones said during the trial: ‘Suddenly, and for no obvious reason, the two defendants crossed the road towards Yusuf and his friends.
‘Yusuf Mohamed had no time to run away, he had no time to do anything to protect himself. Unlike his attackers, he was not carrying a weapon. He stood no chance.’
Haines, who reached him first, acted with ‘brutal efficiency’ as he swung his 6.2in blade at the victim and stabbed him in his heart.
The prosecutor told jurors: ‘Seeing Yusuf collapse to the floor, and as Yusuf desperately tried to retreat, crawling backwards on his elbows, (the 17-year-old) took out his own knife and followed him, stabbing him in the leg as he lay defenceless.
‘As the two young men ran away, tucking their knives back out of sight, they gave each other a fist bump as if to say, ‘Well done us’.’
Police officers are seen collecting evidence outside the convenience store where Mr Mohamed was stabbed to death last year
Jurors heard last week that Haines plunged the blade into the 18-year-old Chelsea fan ‘right up to the hilt, as far as it would go’.
Mr Mohamed died within seconds at the scene.
Jurors were shown ‘distressing’ CCTV footage of the attack on Mr Mohamed outside the Intercontinental Foods shop.
With the help of a police dog officers later found a ruck sack dumped in bushes containing a large blade with a curved and serrated upper edge along with a sheath.
Another weapon was discovered by a dog walker.
Haines, of Acton, west London, had accepted being the person in the CCTV footage but claimed he could not remember the incident in the footage because he had had a drink.
Following the verdicts, the defendants were remanded into custody to be sentenced on February.
Detective Chief Inspector Rob Pack, from Specialist Crime who led the investigation, said the verdicts ‘brought justice for Yusuf and his family’.
‘This was a savage and callous attack where a young man lost his life in a matter of seconds,’ he said.
‘To this day, the motive for the killing is unclear. Both defendants clearly felt they could carry and use knives with impunity. that they congratulated themselves with a fist bump and smiles having so brutally taken a life is beyond comprehension.’
