The Costa Rican coast guard was sweeping the Pacific Wednesday for bundles of cocaine that had been dumped by fleeing smugglers.
The Servicio Nacional de Guardacostas said its crew members had recovered between 200 and 300 kilos in national waters near the border with Panamá.
The agency also managed to stop a fastboat that still had bundles of cocaine aboard and detain three Colombians.
The suspects came to Golfito aboard a Guardacostas patrol boat.
These interdictions are almost routine in the Pacific because Costa Rica has beefed up its patrols and has obtained better equipment. The Pacific also is patrolled by U.S. Navy and Coast Guard vessels and aircraft.
