Operation Opaque: Two more drugs criminals jailed
Two more cannabis farmers have been jailed after a four-year Metropolitan Police drugs investigation.
On Friday Hung Le and Ngat Le were jailed by a judge at the Old Bailey for five years and three-and-a-half years respectively.
The pair were found guilty of conspiracy to produce class B drugs.
Operation Opaque, which began in November 2008, has already led to 18 people from London, Kent, Leicester and Solihull, being convicted.
The police operation targeted drugs importers, wholesalers and growers.
In October 2010, 26 people aged between the ages of 15 and 57 were arrested.
Dozens of business premises and warehouses and more than 15 residential addresses were searched and about £35,000 was recovered.
Specialist equipment was imported through different companies set up by the defendants from countries including China and the Netherlands, said a police spokesman.
The majority of the defendants were drivers, cultivators or wholesalers, and most of the equipment seized from the warehouses and business premises was suitable for producing cannabis in industrial quantities.
Of the 18 convicted previously, sentences have ranged from 15 years to 30 months in jail.
Also sentenced on Friday was Jamie Covington, 28, of Blackheath, south-east London. He received a two-year suspended sentence for conspiracy to produce class B drugs and possession of both class B and C drugs.
