Mexico's Attorney General's Office summoned 50 state police officers from Chihuahua on May 4, 2026, to testify regarding the presence of CIA agents [1].

The investigation marks a significant escalation in tensions over national sovereignty and the perceived overreach of U.S. intelligence operations on Mexican soil. If confirmed, the presence of foreign agents operating without official coordination could strain diplomatic ties between Mexico City and Washington.

The Fiscalía General de la República (FGR) is leading the inquiry into the alleged activities of the Central Intelligence Agency in the northern state [1]. According to reports, the 50 officers [1] were called to provide statements to determine the scope and nature of the U.S. intelligence presence in the region.

President Claudia Sheinbaum addressed the situation, stating that the government is acting consistently across different regions. "Se actúa de la misma forma en los casos de Chihuahua y Sinaloa," Sheinbaum said [3].

The summons comes amid a broader context of legal and diplomatic friction. Luisa María Alcalde mentioned separate issues regarding extradition requests, noting that the U.S. did not prove the urgency of the extradition of Rocha Moya [2].

The FGR has not released specific details regarding the evidence that led to the summons of the 50 officers [1]. However, the move indicates a concerted effort by the current administration to monitor and regulate the activity of foreign agencies within its borders, particularly in states like Chihuahua and Sinaloa where security operations are most intense.

The FGR is leading the inquiry into the alleged activities of the Central Intelligence Agency in the northern state.

This investigation reflects the Mexican government's sensitivity toward foreign intelligence operations during a period of heightened internal security efforts. By summoning local police, the FGR is attempting to verify if U.S. agents were operating clandestinely or in coordination with local law enforcement, which would have significant implications for Mexico's legal jurisdiction and its diplomatic relationship with the U.S.
