Eight people have been found guilty of conspiracy to supply heroin and cocaine in Lincoln.
The conspiracy centred around a property on Bailgate in Lincoln, which was being used to prepare significant quantities of Class A drugs for the Lincoln area.
During a raid at the address, large quantities of heroin and cocaine were found, along with cutting agents, a hydraulic press and heat sealing equipment which was used to bulk out the drugs and repress them in order to maximise profit.
Inspector Jo Fortune said: “This was a sophisticated operation, with all parties entering into an agreement to play their part in the distribution of Class A drugs.
“Class A drugs can wreck lives and impacts on both users and their families. Lincolnshire Police continue to seek out organised crime groups and cut supply networks into our county by targeting the higher market dealers.“
