SAN JOSE/PANAMA CITY, Sept 21 (Reuters) - Authorities in Costa Rica and Panama said on Tuesday they detained more than 40 people suspected of operating a cross-country people-trafficking organization by smuggling migrants overland to the United States. The network handled migrants from Asian and African countries and to a lesser extent people from Cuba, Haiti and Venezuela, according to the Costa Rican security ministry. Panamanian authorities carried out 35 raids and 21 arrests, while on Costa Rican soil 15 operations were reported in border municipalities and another 21 people were captured. An investigation that lasted more than a year revealed that the organization charged each migrant $14,000 to $25,000 to take them to the United States, said Costa Rican Security Minister Michael Soto. In Panama, police agents also confiscated three vehicles and a boat used to transport migrants, the Public Ministry said in a statement.
