A Louis Vuitton male model told a court how he was threatened by a professional rival for sleeping with his girlfriend before he stabbed him to death.

Harry Uzoka, 25, was knifed in the heart by 24-year-old George Koh and died on the pavement in Shepherd's Bush, west London in January.

Koh admits killing Mr Uzoka but claims the victim came to his home with a metal pole and fell on to a knife he was brandishing in self defence.

Mr Uzoka has appeared in shoots for GQ, Zara and Mercedes and had helped out Louise Vuitton model Koh when he was starting out.

But relations between the pair soured and Uzoko arranged to fight Koh to settle their developing feud, which had been brewing over Instagram.

Mr Uzoka believed Koh slept with his girlfriend, Ruby Campbell and later said he wanted to settle the row 'face to face.'

Koh told the court: 'I received a call from Harry getting threats. Harry's girlfriend had followed me on social media.

'Harry called me and said 'I know you slept with my girlfriend. There is no point denying that.

'He said to me: 'you better run, when I see you this is not a joke.'

'I was just trying to explain that I did not sleep with anyone's girlfriend.

'Then after that there were just continuous threats. I showed a couple of friends and there were quite shocked how he was messaging me.'

The court heard how Koh replied saying: 'When you see me, if you want to fight, lets fight.'

Mr Uzoka had got together with Ruby Campbell (pictured) last summer after meeting her on a photoshoot in Los Angeles, a witness said

Koh told the court that three men turned up to his house in the middle of the night, and started shouting up at his window, 'yo, come out.'

He said: 'I was so scared. They were outside for 15-20 mins. I called my friend and told him that this is really getting out of hand.

'Harry had never brought people to my house before.'

Koh, of York Way, Camden, northwest London, has admitted possessing two knives on the day of the fatal attack but denies murder.

It is claimed Koh attacked the victim with two friends, Jonathan Okigbo and Merse Dikanda, both also 24, who were said to be armed.

Okigbo, of Trevithic House, York Rise, Camden, and Dikanda, of no fixed abode, also deny murder.

Dikanda further denies possessing a machete on the day of the attack and possessing a bladed article in a separate incident two weeks later.

Model Chuck Achike (pictured) told the Old Bailey that victim Harry Uzoka had recently been offered a role in a rom-com

Giving evidence at the trial, Mr Uzoka's long-term friend, Chuck Achike, who is also a model, told an Old Bailey jury that Mr Uzoka was in a positive mood when he went to his flat the previous day despite the escalating dispute with Koh.

'He said George said 'He f***** my girl', which I thought was petty and young,' Mr Achike told jurors.

'He knew it wasn't true and I knew it wasn't true.'

He said Mr Uzoka had got together with Ruby Campbell last summer after meeting her on a photoshoot in Los Angeles.

Asked what the mood was like as Mr Uzoka discussed Koh with his flatmates, Mr Achike said: 'It was fine, it was happy, it was normal.

'Harry had always wanted to be an actor and he had just got a role in a British movie and they had just sent him the script.'

Mr Achike said he could not remember the name of the film, but knew it was a romantic fiction.

'It was optimistic, we were talking about the future,' he added.

The trial continues.
