Spanish police working with Britain's Serious Organised Crime Agency have arrested nine suspects in an investigation targeting criminals who allegedly smuggled drugs hidden inside industrial electrical transformers.
The Interior Ministry said to that the gang acquired hashish in Spain and transported it to Britain.
Seven suspects were arrested in Elche and two alleged ringleaders were held in Britain.
Three houses in the Spanish cities of Orihuela and Elche were searched. A sawn-off shotgun with some ammunition cartridges were seized, among other items.
The ministry says the investigation began in January when police were alerted to the existence of a criminal organisation on Spain's east coast.
