Federal authorities say a major drug-trafficking tunnel linking San Diego and Tijuana, Mexico was discovered yesterday.

According to US Immigration and Customs Enforcement spokesman, Lauren Mack, the underground system found yesterday appeared to have been recently built and had not yet been utilized for the purposes of drug smuggling.

The alleged cannabis channel was uncovered by the San Diego Tunnel Task Force, which consists of members of the US Customs and Border Protection and the Drug Enforcement Administration.

Even though US investigators are not saying much about the recent discovery, some reports have surfaced, mostly from Mexican news outlets, indicating the highly developed tunnel was a located in the vicinity of a major Tijuana airport.

In a statement from Tijuana’s public safety chief, Alberto Capella, the investigation is still ongoing; therefore, no details can be provided.

There has been more than 75 drug-smuggling tunnels discovered on the US-Mexico border throughout the past five years. These passageways, mostly concentrated along the border in California and Arizona, have been used as a primary avenue for smuggling large quantities of marijuana across the border.

In fact, one of the largest marijuana busts in US history occurred in 2011, when authorities discovered a total of nearly 60 tons of marijuana on both sides of the border as the result of finding a 600-yard tunnel system.

The latest tunnel is the eighth underground route to be busted in San Diego since 2006. Authorities believe that Mexico’s Sinaloa cartel was responsible for the existence of those illegal corridors.

Investigators say more information regarding this discovery will be released once their investigation is complete.
