The final two members of a major drug gang have been jailed for their part in a plot to bring large amounts of heroin to Devon.
The Liverpool based drug ring was smashed when police carried out a surveillance operation in which they tracked couriers and dealers using a dead letter drop on a late within yards of two Exeter schools.
Another branch of the police inquiry tracked cash as it was paid through a network of accounts in East Devon, Newton Abbot and Exeter and channeled straight up to Liverpool.
In some cases money from the sale of heroin on the streets in Devon back to the North West and was taken out again in cash within minutes.
The police operation, named Cranefly, led to the ringleaders and most senior members being jailed in May this year at Exeter Crown Court.
The final two members of the gang have now joined their co conspirators behind bars after they took part in the high speed money laundering operation.
Fork lift truck driver Paul Ellis, aged 29, and used car salesman George Sweeney, aged 30, both from Liverpool, admitted money laundering and were jailed for two years and 14 months respectively.
Judge Phillip Wassall told them:"You allowed a drugs conspiracy to operate at different levels. Without people willing to launder money the conspiracy could not have worked.
"You both knew you were laundering money from criminal activities even if you averted your eyes as to exactly where it came from."
Miss Mary Cowe, prosecuting, said at the time Ellis had no legitimate source of income but his bank account was used to channel £13,000 in just three months and he had direct links with £6,615 of it.
Sweeney was caught on CCTV as he paid in £2,300 into the Halifax branch in Roman Way in Exeter in February last year just minutes before it was withdrawn in Liverpool.
He told police he had made the money selling second hand cars and it was a legitimate transaction.
Mr Anthony O'Donohoe, defending, said both men had been pawns in a larger operation and had not known it involved class A drugs.
He said they had both moved on to find work and settle down into normal lives, which would be disrupted if they went to jail.
The original trial heard how the heroin supply operation was exposed by a major police surveillance operation.
The gang brought tens of thousands of pounds worth of heroin and used a secret hiding place in Hollow Lane, Exeter, which was just a few minutes drive from the motorway but was also yards away from St Luke's High School and the Ellen Pinkham special school.
The gang recruited desperate addicts in Devon to sell the drugs on the streets and pass it on to Exeter based middle managers, who paid it into banks.
The total size of the operation was never established but was thought to have been worth tens of thousands of pounds.
Ringleader Craig Shaw, from Liverpool, was jailed for eight years in May and eight others have now been jailed for their part in either the conspiracy or the money laundering.
