Mexican federal agents say they have uncovered yet another underground passage pointed at the U.S. border, this time a wooden tunnel discovered beneath a home in Tijuana's Nueva Tijuana neighborhood last Saturday. Officials described the passage as roughly 265 meters long and 6.3 meters deep and said it appeared to be built to move contraband toward the United States.
What officials say
According to Mexico's Attorney General's Office, agents from the Agency of Criminal Investigation carried out a search warrant on the property with support from the Mexican Navy. Inside, they found a timber-lined tunnel that investigators believe was oriented toward the U.S. border.
The agency described the house as a likely hub for storing and trafficking weapons, explosives and illicit substances, noting that the site appeared set up to support organized smuggling operations.
What was seized
During the raid, officers confiscated four cartridges, three cell phones, bank cards, a DVR device and 24 doses of methamphetamine. Authorities say those items, along with other evidence gathered at the scene, have been turned over to the federal public prosecutor's office so the investigation can move forward. That inventory and handoff were reported by NBC 7 San Diego.
A familiar pattern at Otay Mesa
The discovery fits a long-running pattern along the Tijuana–Otay Mesa corridor, where law enforcement on both sides of the line has repeatedly unearthed elaborate cross-border tunnels outfitted with lighting, ventilation and other infrastructure built for high-volume smuggling.
The Los Angeles Times, reporting on a major Otay Mesa tunnel uncovered in 2025, noted that more than 95 tunnels have been found and decommissioned in the San Diego area since 1993, underscoring how entrenched this method has become for large-scale trafficking.
Legal implications
The latest search unfolded within an investigation tied to alleged violations of Mexico's Federal Weapons and Explosives Law and the General Health Law, statutes that Mexican authorities commonly use in narcotics- and arms-trafficking cases. Federal prosecutors in Baja California have taken custody of the seized evidence and will pursue the matter under federal law, as reported by El Universal.
Yesterday, U.S. officials had not issued any public response. NBC 7 San Diego reported that it had reached out to American authorities and was awaiting comment. Mexican investigators say the Federal Public Prosecutor's Office in Baja California will continue the probe and that all evidence is now in federal hands.
