Los Metros is a faction of a Mexican drug trafficking organization known as the Gulf Cartel. The group was formed in the late 1980s during the reign of Osiel Cárdenas Guillén, the former leader of the cartel, to provide security to the organization's leaders as the cartel's armed wing. The leader of Los Metros, Mario Ramirez Treviño, alias X-20, was arrested on 17 August 2013.[1]
