Mexico Launches Probe Into U.S. Involvement in El Mayo Zambada Arrest

The Mexican government has initiated a formal investigation into the 2024 capture of Sinaloa cartel co-founder Ismael “El Mayo” Zambada García. The inquiry addresses growing diplomatic friction following reports from the outlet Pie de Nota, which challenge the U.S. government’s assertion that it did not participate in the operation. While American officials have consistently claimed they were not involved in the seizure, evidence suggests a potential direct role played by the Federal Bureau of Investigation on Mexican soil. The Mexican investigation aims to determine if U.S. agencies violated established legal protocols or breached national sovereignty during the clandestine transfer of the drug kingpin to American custody. This development intensifies pressure on bilateral relations, as Mexican authorities seek transparency regarding the coordination and legality of the arrest that resulted in one of the highest-profile cartel takedowns in recent history.
