The son of one of Mexico's most wanted drug lords has been arrested on drug trafficking charges while entering the United States through Nogales, the U.S. attorney's office in San Diego says.
Serafin Zambada was arrested Wednesday while crossing the border in Nogales, Ariz., with his wife, who was detained and released, agency spokeswoman Kelly Thornton says.
Zambada is scheduled to appear before a federal judge in Tucson on Monday. Prosecutors plan to ask that he be sent to San Diego to face charges.
Zambada is the son of Ismael "El Mayo" Zambada, who survived decades of turf wars and rose to the top of the underworld through savvy deal-brokering.
Ismael Zambada is considered the strategist of the Sinaloa cartel, more involved in daily operations than his better-known boss, Joaquin "El Chapo" Guzman.
