Four men have been jailed at Bolton Crown Court after drugs with a street value of £100,000 were seized by police.
Khalid Mahmood, aged 31, of Morley Street, Bury, James Albert Finlay aged 31, of Balmoral Close, Greenmount, Bury, Darren Hancock, aged 46, of Manchester Rd, Haslingden, Wayne Whiting, aged 30, of Norton Street, Kent, Khalid Mahmood, aged 31, of Morley Street, Bury, and Kabeer Hussain aged 31, of Hey Street, Rochdale, admitted being concerned in the supply of cannabis.
Hancock was jailed for two-and-a-half years Whiting was jailed for 18 months.
Mahmood and Hussain were jailed for two-years-and-eight months.
Finlay was given a nine-month sentence suspended for two years, ordered to carry out 200 hours unpaid work and given a 12-month supervision order.
On Thursday 1 May 2008, Mahmood and Hussain met up with Hancock and Whiting at Roach Bank, Bury. An exchange was witnessed and a package put into the boot of a Peugeot 307.
Whiting left Manchester and travelled on the M6 towards London.
At about 10pm the car Whiting was in was stopped by officers from Greater Manchester Police and Cheshire Constabulary between junction 17 and 18 of the M6.
In the boot of the car were six bin bags of cannabis bush weighing almost 20kg. The drugs had a street value of about £100,000.
The bags were forensically examined and DNA matching Hancock and Finlay was recovered.
Detective Sergeant Nicholas Edge of the Xcalibre Organised Crime Unit said: "The men were involved in a plot to supply a large amount of illegal drugs, which would have undoubtedly hit the streets.
"To make such a large recovery is clearly an excellent result, to get a group of drug dealers locked up is even better."
