Six people aged between 20 and 24 were arrested yesterday on suspicion of importing cannabis.
Earlier this year, Greater Manchester Police launched a proactive operation to tackle a suspected criminal network responsible for drug importation and distribution.
So far, 675.5 kilograms of cannabis have been seized during the operation and Border Force officials have intercepted several parcels. Each package is estimated to be worth just over £5 million wholesale price.
Seizure of £474,000 cash has also been made.
Many roles have been played during the conspiracy including orchestrating the importation of the drugs, selling the drugs to customers across the UK and allowing criminals access to home addresses so that shipments can be sent there.
Detective inspector Claire Rawcliffe said: “We know that organised criminal networks will seek to exploit infrastructure like the postal or fast parcel system to bring their illegal commodities into the UK undetected, but we are working closely and collaboratively with a variety of partners and colleagues to stop them.
“The cost and damage to lives that drugs cause our communities is incalculable, and by working with colleagues at Border Force, we’ve been able to prevent sizable quantities of drugs infiltrating our street and causing further harm and exploitation.”
