MIAMI (AP) _ Five Cubans accused of using spear guns and other weapons to commandeer a fishing boat to Florida were indicted Wednesday on charges of conspiracy and transportation of stolen goods.

Alberto Luis Negrin, 30, was employed by the Cuban government as a mechanic on the 40-foot vessel, which was being prepared for a 20-day fishing trip.

The indictment says Negrin helped four other men hide below deck when the ship set sail. After it was inspected by the Cuban Border Patrol, Negrin ``gave a prearranged signal'' for the four to help him take control of the vessel.

The five were arrested on Aug. 11 after sailing into Key West. They were charged with conspiracy and interstate transportation of stolen property.

Also charged were Humberto Luis Negrin, 27, Manuel Castellon Andarcio, 34, Miguel Angel Bonilla, 22, and Sequiel Perez Valdez, 22.

Each faces up to 15 years in prison and up to $500,000 in fines.

They are being held and will appear before a federal magistrate within a week, the U.S. Attorney's office said.
