FOUR men from the Bury and Bolton areas were arrested as part of a multi-million pound drug investigation in East Lancashire.
Houses searched, drugs and an arms cache seized in Lancashire, Greater Manchester, Cumbria and London.
Twenty-three have been charged with drug conspiracy crimes and tried by Blackburn justices.
These include Anthony Richardson, 38, of Mackenzie Street, Bolton, who has been charged with conspiracy to supply amphetamine.
And Richard Panter, 35, of Longsight Road, Ramsbottom, was accused of conspiring to supply cannabis. Lee Booth, 35, of Holcombe Road, Greenmount, is charged with producing cannabis and Ernest Williams, 55, of Meadow Walk, Farnworth, is charged with obsession, drug delivery and criminal property.
Nineteen others, mostly from Blackburn and Darwen, but with others from Swinton, Carlisle and Barrow, will also be in the dock with the quartet.
Police found 10 kilos of amphetamines and a large quantity of cutting agents in a factory in Hollins Grove, Darwen, which is suspected of being used as a packaging base for drugs.
The investigation also confiscated illegally imported cigarettes, cell phones, hundreds of thousands of pounds of cash and designer watches.
