Three Nigerians were remanded in custody after they pleaded not guilty to charges of importing cocaine and money laundering.
Paul Ugochukwo Offor, 37, who lives in Spain, and Kingsley Wilcox, 31 and Charles Christopher Majimor, 35, who live in Malta, allegedly form part of a drug ring.
Their arrest followed a controlled delivery by the Drug Squad in which a Spanish man who cannot be named by court order was arrested.
