Customs Surveillance vessels Arao and Cormorán boarded a planing boat approaching the Murcia coast near Cabo de Palos on the night of 7 May 2009 and seized more than 4,500 kilos of hashish.[1] The 13-metre boat, fitted with four 250 hp engines and carrying two high-end vehicles, was intercepted in the rugged roadless Calblanque area, where bales must be carried out on foot; six foreign nationals were arrested.[1]

The Civil Guard joined the continuing operation with helicopter and ground patrols, and the agency said further arrests were expected.[1]
