Joaquin “El Chapo” Guzman, the head of one of Mexico’s most powerful drug rings, the Sinaloa cartel, has been arrested in Mexico. Guzman was captured in a joint operation by Mexican marines and the Drug Enforcement Administration at a hotel in Mazatlán, a beach resort town. According to U.S. officials, the operation had been ongoing for four or five weeks. Guzman was wanted in the United States for multiple federal drug trafficking charges and was named a Public Enemy No. 1 last year by the Chicago Crime Commission.
