Costa Rican authorities announced Thursday the seizure of 1,068 kilos (2,352 pounds) of cocaine aboard a fishing boat off the country's Pacific coast.

The Costa Rican-flagged vessel was intercepted Wednesday by U.S. Coast Guard units about 500 kilometers (310 miles) from shore under an accord between Washington and San Jose, the Security Ministry said.

Once aboard the boat, Coast Guard personnel found the cocaine and took the four crew members, all of them Costa Rican citizens, into custody.

The Coast Guard units will rendezvous with a Costa Rican government vessel to turn over the drugs and the suspects, the Security Ministry said.

In a separate operation, inspectors at the Peñas Blancas border crossing found 138 kilos of cocaine hidden inside a cargo truck with Honduran plates that entered Costa Rica from Nicaragua.

The truck driver, a 33-year-old Honduran national, was arrested.

Authorities at the Peñas Blancas post have seized 2.8 tons of cocaine this year, more than 20 percent of the total amount of the drug confiscated nationwide, the Security Ministry said. EFE
