NOGALES, Ariz. -- Federal authorities said they've shut down a drug-smuggling tunnel discovered in a backyard in southern Arizona.
Members of the Nogales Tunnel Task Force developed information that a drug-smuggling tunnel was located at a Nogales house about 1 1/2 miles north of the international border.
Authorities discovered the tunnel entrance in a shed.
U.S. Immigration and Customs Enforcement officials said the crude, hand-dug tunnel was approximately 52 feet long and roughly 2 feet wide by 3 feet tall with some wood shoring.
The tunnel ran to an underground sewage line that ultimately crossed the international boundary.
No people or drugs were found inside the passageway. Authorities seized eight pounds of white heroin, three pounds of marijuana and more than $1,400 in cash from the house.
