Sineidin Corrins, depute procurator fiscal for specialist casework at the Crown Office, said: “This is a significant prosecution. These two individuals played pivotal roles in a coordinated operation to distribute illegal and harmful drugs.

“With this conviction, we have removed these drugs from the streets and made communities safer.

“This successful prosecution underscores our determination to continue to disrupt serious organised crime.”
