Two individuals were detained, and three soldiers were injured during the operation, Sedena reported.

The operation involved multiple aircraft from the Fuerza Aérea (Air Force) and the Fuerza Especial de Reacción Inmediata of the Guardia Nacional (National Guard), Sedena stated. Military personnel were attacked during the operation and returned fire. The authorities have initiated forensic investigations to confirm Oseguera’s identity.

In Guanajuato, the Secretaría de Seguridad y Paz reported fires at pharmacies and convenience stores, with no reported injuries but significant property damage. A coordinated security deployment involving the Army, National Guard, and local police has been launched in response.
