Costa Rican authorities say they have dismantled a cocaine smuggling network that used fishing vessels to ship drugs from Ecuador and Colombia through Central America and into Mexico.

The Security Ministry says in a Sunday statement that the Colombian-run network paid fishermen to haul cocaine to Guatemala and Mexico.

The ministry says raids in the Costa Rican capital of San Jose and in the Pacific coast city of Puntarenas were carried out Saturday. Five Colombians and a Costa Rican national were arrested.

Costa Rican officials say powerful drug cartels are increasingly using the country as a transshipment point for cocaine — much of it ultimately bound for the United States.
