Border Patrol Shuts Down Sophisticated Drug Tunnel Connecting Tijuana to San Diego [WATCH]

According to a statement from U.S. Customs and Border Protection (CBP), the tunnel spanned approximately 2,918 feet in length, reached depths of 50 feet underground, and measured 42 inches in height and 28 inches in width, as reported by The New York Post.

The passage was outfitted with lighting, electrical wiring, ventilation systems, and a track system designed for the efficient transport of narcotics.

The tunnel’s entrance was discovered inside a residential structure in the Nueva Tijuana neighborhood of Tijuana. CBP officials said the entrance had recently been concealed using newly installed floor tile in an apparent attempt to hide it from law enforcement.

Authorities described the tunnel as “highly sophisticated,” noting that barricades had been placed within it, likely to delay or obstruct detection by law enforcement. The projected exit point was located near or inside a commercial warehouse space in San Diego.

Acting Chief Patrol Agent for the San Diego Sector, Jeffrey D. Stalnaker, emphasized the broader national security implications of the discovery.

“As we continue to strengthen the nation’s air and maritime border security, it’s not surprising that foreign terrorist organizations would resort to underground routes,” Stalnaker said in a statement.

“Disruption of narcotics smuggling tunnels is critical to protecting American lives.”

In response to the discovery, CBP announced that thousands of gallons of concrete will be poured into the tunnel to render it inoperable and prevent its future use by criminal or terrorist organizations.

Since 1993, more than 95 drug tunnels have been located and dismantled in the San Diego region alone.

This latest discovery highlights ongoing efforts by transnational criminal groups to exploit underground infrastructure in order to bypass border security and move contraband into the United States.

CBP did not immediately respond to media inquiries regarding the status of ongoing investigations tied to the tunnel.
