ic findings reveal the discovery of an sophisticated underground tunnel near the U.S.-Mexico border that appears designed to facilitate cross-border criminal operations. The passageway, located in Tijuana’s Nueva Tijuana neighborhood, measures approximately 265 meters long and extends 6.3 meters underground. Mexican authorities identified advanced infrastructure within the tunnel, including lighting and ventilation systems, along with an electronic mechanism for transporting goods between nations.
The investigation was conducted by Mexico’s Attorney General’s Office (FGR) Criminal Investigation Agency in coordination with the Security Cabinet, following a search warrant at the property. Authorities linked the site to alleged violations of firearms and explosives laws as well as drug trafficking charges, suggesting it functioned as a logistics hub for narcotics, weapons, and explosives. Evidence recovered included ammunition, suspected methamphetamine and marijuana, cell phones, and documents, all of which have been transferred to federal prosecutors in Baja California for further proceedings.
Mexican officials believe the tunnel connects to a street in San Diego, though they have not disclosed the specific location or confirmed whether the U.S. side has been located. The discovery represents a significant setback for criminal organizations relying on such underground routes to smuggle contraband across the border.
The investigation into potential connections to U.S. soil continues as authorities work to determine the full scope of the operation and its links to broader criminal networks in the region.
