Seven men aged 23, 28, 31, 39, 45, 47, and 53 were arrested today in Paisley, Johnstone and Lanarkshire, with the further arrest of a 45-year-old man in the Lincolnshire area.
A total of 20 people have now been arrested following the cross-border operation focusing on the alleged importation and distribution of Class A and Class B drugs through Glasgow and the west of Scotland, police said.
Around £7m of drugs, mainly amphetamine and cocaine, have been seized by officers since the start of the operation five months ago.
Detective Chief Superintendent John Cuddihy, said: “Police Scotland remains absolutely determined to rid our communities of serious and organised criminal gangs and we will continue to relentlessly target those involved in the sale and supply of controlled drugs.
“Hundreds of kilograms of amphetamine have already been seized and significant amounts of class A and class B drugs have been taken off the streets of the west of Scotland.”
