Greece's coastguard released on Saturday (April 8) footage from an operation that uncovered an international ring that transported large quantities of drugs from Albania to Italy using high-speed boats. br br The coastguard's drug-fighting unit said five Albanians and two Greek had been arrested on Friday (April 7), while two speedboats and 1.5 tonnes of unprocessed cannabis were seized. br br Members of the ring - which Greece's coastguard said was estimated to have made "many millions of euros" - were apprehended as they entered Greek waters after leaving packages of cannabis wrapped in plastic on a beach in southern Italy, according to the coast guard. br br The months-long investigation, in cooperation with Italy's Guardia di Finanza, found that the ring purchased large volumes of drugs in Albania and transported them on customised high-speed vessels to the shores of Italy.
