Arrests have been made after "smuggled" Albanian migrants were discovered working at a cannabis farm in Wigan, as the National Crime Agency issued an appeal for a man with links to Manchester.
Detectives have detained the suspected boss of an organised crime group that uses trafficked Albanian nationals to farm cannabis across the North West during a sting operation this week.
It comes after three farms were discovered which were being mined by migrants in Leigh in Greater Manchester, Blackpool in Lancashire and Prestatyn in North Wales.
