A 33-year-old man has been jailed for his part in a conspiracy to supply cocaine worth more than £5million.
Anthony Matthews, of Manor Road in Chigwell, was sentenced to nine years at Snaresbrook Crown Court.
He pleaded guilty on June 8 to conspiracy to supply Class A drugs with four other men, each of whom had previously been sentenced.
Anthony Matthews was seen by police officers handing over a suitcase to Darren Angol and another man in Wick Lane, Bow, in July 2012.
Later that day, police stopped Angol in the Islington area.
He was in possession of 2.46kgs of cocaine, with a street value of more than £450,000.
The same day, and on two subsequent days, Matthews was seen exchanging bags with Danny Bradshaw in the car park of a McDonald's restaurant in Canary Wharf.
Several weeks later, Matthews met with Charlie Court in in Cheshunt and he was seen leaving the vehicle carrying a rucksack.
On August 28, police stopped Court as he drove to a meeting with Matthews.
He was arrested and, during a subsequent search, 27kgs of high grade cocaine was found behind a hidden wall at his business address in St James Lane, Goffs Oak, Hertfordshire.
The drugs had a street value of up to £5million.
A search warrant was executed on May 7 at Matthews's apartment in Manor Road and 352 grams of cocaine was found hidden in a bedroom.
The drugs had a street value of around £140,000.
