Portuguese marines operating from the patrol vessel NRP Drago intercepted two high-powered semi-rigid boats in international waters about 70 nautical miles (130 km) south of mainland Portugal.[1][2] An Air Force maritime patrol had tracked the boats’ suspicious movements before the Navy closed in and boarded them.[1][2] The operation seized around 8,600 kg of hashish and led to the arrest of eight men aged between 34 and 40.[1][2]

The seized boats were escorted to the port of Faro, the nearest port, so the investigation could continue on land.[1] The detainees were to be presented to the judicial authority, and the Judiciary Police kept the investigation.[1] The joint operation brought together the Navy, the Air Force, the Maritime Authority and the Judiciary Police; a second boat was stopped about 80 nautical miles off the coast.[1][2]
