Sheinbaum Announces Arrest in Buenos Aires of Former Navy Admiral Farías Laguna for Leading Huachicol Smuggling Network

President Sheinbaum announced at the April 24 mañanera the arrest in Buenos Aires, Argentina, of former Rear Admiral Fernando Farías Laguna, accused of heading a large hydrocarbon-smuggling (huachicol) network linked to the previous administrations. Argentine authorities detained him after he entered the country illegally using a false passport — a significant detail suggesting premeditated flight from Mexican justice. Sheinbaum confirmed the Foreign Affairs Ministry (SRE) and the Attorney General's Office (FGR) are formally requesting Argentina deport Farías Laguna to Mexico; if Argentina declines deportation, Mexico will initiate formal extradition proceedings. The arrest represents a notable anti-corruption enforcement action targeting military personnel accused of involvement in fuel theft — an endemic problem in Mexico. Huachicol networks (illegal fuel tapping from PEMEX pipelines) peaked between 2017 and 2019, costing Mexico an estimated 60 billion pesos annually at their peak before a major crackdown under AMLO reduced losses by roughly 90%. Farías Laguna's alleged leadership of a huachicol network tied to the prior administration fits the Fourth Transformation's anti-corruption narrative. The FGR classified him as a fugitive after he evaded Mexican arrest; his Buenos Aires apprehension was the result of an international alert. The case will test Mexico-Argentina extradition cooperation under the Milei and Sheinbaum administrations, whose governments have otherwise had ideologically cool relations.
