Four men have been arrested in connection with £1.5 million gold and computer theft.
The suspects were detained in north Belfast as part of a Europe-wide investigation into the theft of two ship cargoes last year.
Four other men arrested in June in relation to the missing shipment of gold and shipment of computers have been charged with fraud, deception and handling stolen goods.
