A Northenden man was among four to be jailed for conspiring to flood the streets with £4.5million of class A drugs.
Raymond Gilham aged 30 from Longley Lane, Northenden was sentenced to 8 years 8 months for conspiracy to supply class A drugs.
Shaun Morfitt aged 36, of The Grange, Cleveland, was sentenced to 18 years; Dean McCaffrey 30, from Brede Walk, Sale, to 22 years and Colin McCaffrey 31, Bank Street, Golbourne to 22 years.
The four were sentenced as part of Operation Petral, a crackdown on the supply of class A drugs and organised crime in Manchester, Preston and Cleveland between March and October 2015.
In September 2015 a vehicle was stopped travelling from Manchester to Cleveland with a hidden compartment containing two kilos of cocaine.
On the same day police raided an address in Northenden where six kilos of cocaine and approximately three kilos of heroin were seized.
In October 2015 police searched an address in Droylsden where a kilo of cocaine was recovered inside the property.
A further kilo of cocaine was recovered later in the day from a vehicle in the Droylsden area.
Further enquiries revealed the group had been involved in the distribution of £4.5million of class A drugs.
Detective Inspector Rob Cousen, of GMP’s Serious and Organised Crime Group, said: “Drugs cause widespread damage in the community and they will not be tolerated.
“I hope that this sentence sends the message that we relentlessly pursue and dismantle organised groups that seek to profit from flooding the streets with these substances.”
“I want to pay tribute to the operational teams across the Country who worked together, playing a vital role in finding and convicting these men.”
