The authorities have arrested 12 people in Spain, Britain and Dubai.
Spanish customs officials say in recent years they have found cocaine in breast implants, a wig and even a plaster cast encasing a man`s broken leg.
Police suspect that smugglers used a charcoal company in Spain as a front to import the cocaine.
The drugs were then extracted from pallets and charcoal, processed and distributed around Europe.
Spain is seen as the main entry point in Europe for drug smugglers from South America.
