SAN DIEGO (FOX 5/KUSI) — An underground tunnel has been found connecting San Diego and a property in Tijuana. Mexican authorities say it was used as a storage, logistics, and trafficking center for weapons, explosives and illegal drugs, according to the federal Attorney General’s Office (FGR) in Tijuana, Baja California.

The excavated tunnel is 265 meters long, and 6.30 meters underground, with lights, ventilation and an electronic sliding mechanism that goes across the floor in both directions from Mexico to the U.S. According to the investigation, the tunnel is believed to connect to a well-known street in San Diego.

The tunnel was found after a search warrant was served on a home in the Nueva Tijuana neighborhood for violations of the Federal Law on Firearms and Explosives and the General Health Law.

During a search of the Tijuana home, located just across the U.S.-Mexico border south of Otay Mesa and State Route 905 in southern San Diego, authorities confiscated cartridges, suspected methamphetamine, marijuana, cell phones and various documents, according to the FGR, leading authorities to determine the home was possibly functioning as a storage, logistics and trafficking center.

The property and all evidence collected were seized and made available to the Public Prosecutor’s Office in Baja California, which will continue with the investigation.

The tunnel was discovered through a coordinated effort with the Attorney General’s Office (FGR), in the city of Tijuana, Baja California, the Security Cabinet of the Government of Mexico, the Criminal Investigation Agency (AIC) of the FGR, and the Federal Public Prosecutor’s Office (MPF) of the Federal Prosecutor’s Office in Baja California.
