Homeland Security Investigations special agents found an 82-foot-long tunnel that has been used for a few months to smuggle drugs near Nogales, Ariz.
Agents on the Border Enforcement Security Task Force were executing a search warrant when they discovered the tunnel, according to KOUN9-TV.
The tunnel, which was 8-feet-deep and had a ventilation system, led from a house in Nogales to a wastewater pipeline in Rio Rico, Ariz.
The tunnel appeared to have been used by Mexican nationals, two of whom were arrested on charges of possession and conspiracy to distribute hard narcotics.
Agents seized 200 pounds of meth, more than 6.5 pounds of fentanyl, nearly two pounds of heroin, and nearly three pounds of cocaine.
