Detective Inspector Mitch Leach, who leads the Serious and Organised Crime Unit, said the group had led an 'organised and sustained' operation.
He said: "Between November 2016 and June 2017, the team worked closely with teams from Doncaster and the Roads Policing Group to observe and disrupt this group, who were identified as involved in a conspiracy to supply large quantities of cocaine and heroin.
“During that time, the team carried out surveillance work, executed a number of warrants and stopped several vehicles, as they gathered evidence to get this case to court.

“John Paul Finn was found to be the leader of the group, primarily based in Edlington, Doncaster. We believe he was in charge of the operation, directing couriers to collect and deliver drugs between Doncaster, Wakefield and Warrington.
“Barton was identified as the supplier from Warrington, while the second source of drug supply was led by Khalique and Hussain in the Wakefield area.
“The case was built around evidence compiled over a number of key dates, where drugs and cash were seized.
“Throughout the investigation, the team stopped cars and carried out warrants, finding extensive amounts of cocaine - with a 90 per cent purity - heroin and also cash. This, accompanied with surveillance work and telephone data, meant they were able to identify everyone involved, arrest and charge them.
“In total, £300,000 worth of cocaine and heroin was seized, along with and £80,000 in cash.
“This was an organised and sustained operation, where the group members were moving large amounts of high purity Class A drugs and selling to members of the public.
“This result is significant, with the group now serving over 100 years behind bars between them, and officers across the unit led by Detective Inspector Graham Bulmer at that time, worked tirelessly to secure evidence to enable this case to progress before the courts.
“No matter how sophisticated or organised a drugs operation may be, or appear to be, our specialist team is committed to identifying those involved, disrupting their organisation and bringing them before the courts to be held to account.”
