TIJUANA (KGTV) — Mexican authorities found a tunnel in Tijuana that likely connects to a well-known street in San Diego, according to Mexico's Attorney General's Office.
The tunnel measures around 869 feet long and 21 feet deep and has operational infrastructure, including lighting and ventilation.
Mexican authorities carried out a search warrant at a residence in Nueva Tijuana for a "violation of the Federal Law on Firearms and Explosives and the General Health Law."
Authorities say that the property was possibly functioning as a storage, logistics, and trafficking center for weapons, explosives and illicit substances. They say they located cartridges, suspected methamphetamine, marijuana, as well as cell phones and various documents.
ABC 10News reached out to the Department of Homeland Security concerning the discovery:
“Special Agents with Homeland Security Investigations (HSI) in San Diego, in coordination with our Homeland Security Task Force (HSTF) partners, are conducting a criminal enforcement operation involving a cross-border subterranean tunnel in Otay Mesa, CA. To protect the integrity of the ongoing investigation and ensure the safety of all involved, we are unable provide additional details at this time.”
The evidence and property were placed under custody, according to Mexico's Attorney General's Office.
The investigation into the tunnel continues.
