Clive Andrews, aged 57, of Cherry Tree Court, Moira, Derbyshire was jailed for seven years.
The investigation into the wholesale supply of class A controlled drugs in Northamptonshire started when Beasley was arrested on August 2016 and found in possession of one kilo of high purity cocaine that had had been blocked, stamped and imported from outside of the UK.
At the time he was en-route to meet Andrews in Derbyshire, having met Richard Gray earlier in the day.
Investigators found 14 key dates prior to his arrest where he is believed to have made further exchanges of cocaine of a similar value.
The main subjects of the conspiracy were Morales, and Richard Gray. Moylan acted as a right hand man and currier whilst Beasley acted as a courier, both working on behalf of Morales, based in Northampton.
The upstream supplier, Richard Gray, was supported in his activities by his brother, Raymond Gray.
In December 2016, officers carried out warrants on five of the defendants’ addresses.
During the search of Andrew’s address, they discovered a large amount of cash, over 1.5 kilos of cocaine, cutting agents and other articles for use in processing and distributing drugs. This included mixing equipment and a hydraulic press.
It is believed that this is the address used to adulterate and repackage their product for onwards sale.
Detectives found Moylan had made numerous bank transfers to Richard and Raymond Gray as payments from Morales.
Moylan received £82,282 in cash credits over 22 months. £55,000 was transferred to Richard Gray and £11,150 to Raymond Gray.
Emily Sharpe, an investigator with EMSOU (East Midlands Special Operations Unit) said: “We’re very pleased indeed with the sentences handed down by the judge today.
“These men were part of a serious and organised crime group who were in action for a lengthy period of time.
“Their organisation was well planned and professional and we are pleased that such a thorough investigation has put an end to their long term criminal activity and disrupted a drugs supply chain that, ultimately, cause so much misery to so many people.”
