A criminal gang whose drugs operation was unravelled when they were caught near Doncaster have been jailed for a combined total of more than 100 years.
Police forces across the East Midlands and the north of England were involved in the detection of the conspiracy, seizing kilos of amphetamine and cocaine in the process.
A total of 12 people were convicted for their involvement in the plot and they were sentenced at Nottingham Crown Court on Friday.
The plot began to unravel in July last year when a van was stopped on the A1 near Doncaster containing ten kilos of amphetamine, worth an estimated £227,000.
The resultant investigation linked the drugs to a store in Sutton-in-Ashfield, Nottinghamshire, and a warrant was executed at the shop a few weeks later.
Officers from Nottinghamshire Police and the East Midlands Special Operations Unit discovered over seven kilos of a substance in residue form which contained amphetamine in buckets, drains and toilets within Protein Masters.
Also recovered was a vacuum packing machine and mixing tools, similar to those used in the construction industry.
A number of suspects pleaded guilty to charges of conspiracy to produce or supply class A and B drugs. Six others had denied drugs offence charges but were convicted by a jury following an eight-week trial at Nottingham Crown Court.
Jail terms handed to gang members ranged from 18 years and eight months to one year.
None of those sentenced were from the South Yorkshire or Isle of Axholme area.
