Spanish police say they have broken up a gang suspected of selling forged passports and resident cards for entry into the United States, arresting 14 of its members.

The organized group was allegedly composed of Cuban nationals who charged between 1,000 and 1,500 euros ($1,340-$2,010) per forged document. They used a travel agency to attract potential customers, especially from among the Cuban community based in the Canary Island of Tenerife.

Officers arrested 11 Cubans and three Spaniards in Tenerife and Madrid, a police statement says Sunday.

The investigation began when agents learned of the existence of an organization based in Tenerife but that operated throughout the country and was dedicated to the falsification of official documents.
