A father-of-four was gunned down by a stranger after 'disrespecting' his killer in a McDonald's queue.

Raymond Mitchell, from Thornton Heath, was shot at three times but hit twice in the thigh and abdomen, after an argument spilled out from the McDonald's in Brixton Road, Brixton, into the street.

Yesterday at the Old Bailey, the court heard Horace Campbell, 27, ordered a friend to bring him a gun after clashing with Mr Mitchell at the end of a night out.

Witnesses heard the victim claim Campbell, of Tovil Close, Anerley, had 'tried to diss him,' while Campbell told a bystander Mr Mitchell had been 'too disrespectful.'

Jurors were told he was overheard on his phone telling someone to bring a 'strap' and balaclava.

Minutes later, shortly after 6am on April 17, Liam Douglas-O'Callaghan, 18, is said to have arrived outside the restaurant with a loaded handgun.

Zoe Johnson prosecuting, said the killing had been 'arrogant and audacious.'

She said: "This was a murder carried out in broad daylight and witnessed by a number of people. Neither defendant tried to hide their identity.

"At this stage the evidence indicates it was Campbell who fired the fatal shots but they were both acting together."

Mr Mitchell, who also used the name Devon Scarlett, had been on his way home from a night out in the West End when he ran into Campbell.

CCTV footage showed both men entering the branch within minutes of each other, after Campbell had left the nearby Fridge bar.

The court heard Mr Mitchell confronted a group of men who were arguing loudly in the restaurant, telling them to 'behave.'

"One of this group said to another he would go and get his "thing," meaning his gun," said Ms Johnson.

The court heard Mr Mitchell heard the exchange and said something to the effect of "look, one of these men is going to go and get a gun."

"What happened then was Campbell went to this group and told Devon Scarlett he shouldn't say things like that.

"Here you have a bizarre situation of Campbell and the deceased getting involved in somebody else's argument," Ms Johnson added.

Both men then squared up to each other, removing their watches and valuables and began trading insults before being ejected by security guards out of two different exits.

The court heard Mr Mitchell wouldn't leave at first and would go into the middle of the road and then come back.

At the same time Campbell was on the phone telling Douglas-O'Callaghan of William House, Tulse Hill, to bring a gun to the area, the prosecution said.

The two men agreed to have a show-down in nearby street Marcus Garvey Way, when Douglas-O'Callaghan is said to have handed the firearm to Campbell.

Mr Mitchell was pronounced dead at King's College Hospital hours later at 12.30pm the same day.

Both defendants deny murder. The trial continues.
