A third cross tunnel running beneath the Arizona-Mexico border was found this week. 

Immigration and Customs Enforcement officials described this tunnel as a sophisticated version of cross border tunnels commonly used to smuggle narcotics.

It connected from a home in Nogales, Arizona, adjacent to the border to the international outfall interceptor. That’s the enormous cross border line that carries sewage from both Nogales Arizona and Mexico to a treatment plant in Rio Rico.

This tunnel had a ventilation system made with reinforced tubing and a crawlspace. 

ICE agents found more than 200 pounds of methamphetamine, heroin, fentanyl and cocaine inside. Two Mexican men were also arrested and face charges in U.S. District Court in Tucson. 

Two other tunnels, one incomplete, were also found in the Nogales area earlier this month.
