Six men have been arrested after cocaine with a street value of £100m was found inside sacks of coconuts.
The consignment of coconuts came from Guyana
Half-a-tonne of the Class A drug was stacked in a lorry parked outside Spitalfields Market in east London.
Customs and Excise officers arrested the men on Thursday night following the seizure, which was part of an intelligence-led operation.
The consignment of coconuts was imported from Guyana before being delivered to the market.
Duncan Stewart, assistant chief investigation officer, hailed the operation as a huge success because of the high street value of the drugs.
He said: "As a result of this operation, Customs have successfully stopped a huge quantity of cocaine being sold on London's streets, the proceeds of which
would undoubtedly be used to fund further crime.
"This is an extremely successful operation".
Inquiries into the incident are continuing, he added.
