Three men and a woman have been jailed for their involvement in a drugs line operating through the Black Country which saw kilograms of cocaine and large sums of cash change hands.
Kudakwashe Mutanga, from Wolverhampton, orchestrated the supply of over 81kg (178lbs) of cocaine and was involved in over £3m in cash exchanges, West Midlands Police said.
Others helped move the money and drugs, while former probation officer Dorcas Chiradza from Leicester, accessed systems to gain information on the defendants, the force added.
