NOGALES, Ariz. (AP) - Authorities say another drug tunnel has been discovered along the U.S.-Mexico border.
Homeland Security Investigations special agents and task force officers on the Border Enforcement Security Task Force say the latest tunnel was found late Tuesday night in Nogales, Arizona.
They say the 8-foot deep tunnel runs from a house and stretches 82 feet to the entrance of a wastewater pipeline that runs from Nogales, Sonora, Mexico to Rio Rico, Arizona.
The reinforced passageway features a sophisticated ventilation system equipped with tubing reinforced by beams allowing for crawlspace.
Special agents estimate the tunnel has been in existence for a few months due to the advanced construction and material used to excavate.
Authorities executed a search warrant and seized nearly 200 pounds of methamphetamine, almost 2 pounds of white heroin, close to 3 pounds of cocaine and over 6 ½ pounds of fentanyl.
They also arrested two Mexican men on suspicion of possession and conspiracy to distribute hard narcotics.
On Dec. 11, Mexican authorities located a small, clandestine border tunnel in Nogales, Sonora.
