A robber from Shepherd's Bush faces years in prison for taking part in a lucrative armed heist at Heathrow airport.
Barry Hibberd and three other men were found guilty on Wednesday of the warehouse robbery six years ago, in which they escaped with more than £1m in sterling and £700,000 in foreign currency.
Members of the six-strong gang were already under surveillance by Flying Squad officers when they targeted the Menzies warehouse in February 2004, but detectives could not stop the night-time raid from happening as they did not know when the men would strike.
The seasoned criminals gained access to the air-side site with help from an insider, Darren Brockwell, who gave evidence against all four at the first judge-only trial at the Old Bailey.
Once inside Ohe men tied up 16 workers in plastic handcuffs, pistol-whipped two of the workers, and shot at one man as he tried to escape.
The gang got away with seven bags of cash after stealing a car at gunpoint, and Hibberd and two others celebrated their success that night at the Days Inn Hotel near Heathrow.
But a CCTV still circulated from the hotel eventually helped trace Hibberd, 43, of Goldhawk Road, who was spotted by police driving a BMW X5 in May 2006.
Hibberd was due to be sentenced at the Old Bailey on Wednesday, along with fellow robbers John Twomey, 62, of South Ruislip, Peter Blake, 57, of Notting Hill, and Glen Cameron, 50, of Northolt.
Blake was also found guilty of attempted GBH after shooting at the fleeing worker. A violent scuffle resulted in which two further shots were fired, and the victim at one stage managed to get hold of the gun and tried to shoot at Blake, but the gun jammed and the man was overpowered.
Blake was later identified using DNA tests on a piece of pink latex foam from the mask and the black woolly hat he was wearing, and was caught in July 2005 after being arrested for a separate matter.
Twomey handed himself in days after the robbery following a police appeal, and Cameron was discovered hiding in a caravan site in Cornwall in March 2007.
Detective Superintendent Stuart Cundy, head of MPS Flying Squad, said: "Today's conviction of John Twomey, Peter Blake, Barry Hibberd and Glenn Cameron is the conclusion of a six year investigation.
"These are dangerous individuals who organised a complex armed robbery to steal a substantial amount of money, and expected to get away with it. They were prepared to not only carry guns, but to use them to ensure their plan succeeded."
He added: "I pay tribute to the victims of this violent robbery who provided evidence in this case. I have no doubt that these men would have continued to pose a risk to the public if they had not been caught."
