BISBEE, Ariz. (AP) — Federal officials say a tip led to the discovery of an underground smuggling tunnel connecting a small town in Arizona to Mexico.
The investigation began Monday, when federal authorities alerted Bisbee police that they had received a tip about a drug shipment moving through the small mining town. Bisbee police pulled a truck over on Monday evening just outside the city. A Border Patrol canine found more than 4,700 pounds of pot bundled and stacked in the rear of the truck.
Agents from Homeland Security Investigations, a component of Immigrations and Customs Enforcement, then obtained a search warrant for house in Naco, Arizona, which sits on the border with Mexico.
Agents on Tuesday found an underground tunnel inside a small shed on the property. A special Border Patrol unit was dispatched and investigated the tunnel. The tunnel is equipped with a hydraulic lift and is large enough for an adult to stand in.
Mexican authorities are now looking for the other end of the tunnel, according to a news release.
Authorities have detained two men in connection to the investigation but have not yet named them.
Mexican drug cartels have for many years used tunnels to smuggle drugs and humans in to the U.S. Authorities have found and destroyed more than 80 tunnels connecting Mexico to the United States since 2006. Most are in California and Arizona.
