Argentina’s Naval Prefecture, the coast guard, and the Buenos Aires provincial police intercepted a Paraguayan-flagged vessel called the Papu Sur at kilometre 290 of the Paraná river, off Vuelta de Obligado in San Pedro partido.[1] Officers detained the captain and eight other crew members, all Paraguayan nationals.[1] A search of the containers found more than two tonnes of marijuana, the national security ministry said.[1] Security Secretary Sergio Berni said the scan had confirmed 2,000 kg of marijuana so far, with more than 120 containers still to be checked.[1]

Investigators said the boat had left Puerto Fénix near Asunción bound for Buenos Aires, carrying a drug cargo.[1] Federal judge Alberto Santamarina of Lomas de Zamora ordered the operation after a multi-month investigation.[1] Berni said the provincial police had been investigating a transnational drug gang and called the interception a new smuggling route into Argentina.[1]
