TYSON Fury's cousin was murdered with a single blow from a seven-inch knife after a brawl erupted outside a bar, a court heard.

       Liam O'Pray, 22, is accused of stabbing Rico Burton, 31, with a lock-knife in a brutal attack lasting just seconds.

       Rico died after the blade of the knife, which flicks out using a button, severed the major carotid artery in his neck, causing major blood loss.

       His mum and loved ones wept at Manchester Crown Court as CCTV of his final moments was shown to jurors.

       The fight erupted between O'Pray and Rico's friends in Altrincham, Cheshire, on August 22 last year.

       O'Pray had been drinking in a bar in an area known as Goose Green but told a doorman he would "cause him an issue" after being refused entry later in the night, it was said.

       Witnesses described him as a "loose cannon" and "very erratic" after he was barred from entering a second bar.

       Jurors were told he was pushing people around while trying to look for his phone before a bouncer "dumped" him outside.

       O'Pray then continued his "belligerent and aggressive" behaviour before "absolute chaos" broke out at around 3am, it is alleged.

       His pal Malachi Hewitt-Brown was punched by Rico's cousin Chasiah Burton.

       After Rico aimed a punch at him, O'Pray stabbed him in the left side of his neck, it was said.

       Harvey Reilly, 17 at the time and now aged 18, was allegedly slashed twice - once to the arm and once to the stomach - by O'Pray after stepping in.

       The court was told the defendant was then knocked out as Rico was seen struggling to breathe and holding his neck.

       He was rushed to hospital after going into cardiac arrest where he was declared dead shortly after.

       Michael Brady KC, prosecuting, said: "All this happened within five to six seconds of Chasiah Burton punching Mr Hewitt-Brown.

       "It was an extremely fast-moving incident."

       A post mortem revealed Rico had suffered a 6cm deep cut to his neck that had caused a massive haemorrhage.

       Harvey had a 14cm gaping wound to his chest wall, exposing his ribs, and large wound to his left arm.

       Jurors were told cannabis, cocaine and ketamine were found in O'Pray's bloodstream after the horror.
