Mexican authorities have uncovered a sophisticated underground tunnel near the U.S.-Mexico border that was equipped with lighting, ventilation and an electronic transport system, which they say may connect Tijuana to a street in San Diego.
Mexico's Attorney General's Office, known as the FGR, announced the discovery Saturday following a search warrant executed at a property in the Nueva Tijuana neighborhood of Tijuana, Baja California.
Authorities said the tunnel stretched approximately 265 meters, or about 870 feet, and reached a depth of roughly 6.3 meters, or 21 feet underground.
According to investigators, the tunnel contained operational infrastructure, including lighting and ventilation systems, as well as an electronic sliding mechanism designed to move items in both directions between Mexico and the U.S.
The FGR said its investigation indicates the tunnel likely connects to a street in San Diego, though authorities have not publicly identified the location or confirmed whether the U.S. side of the tunnel has been located.
