ICE HSI investigation leads to discovery of Arizona smuggling tunnel

NOGALES, Ariz. — An active drug smuggling tunnel was located and shut down here Tuesday following a multi-agency probe spearheaded by U.S. Immigration and Customs Enforcement's (ICE) Homeland Security Investigations (HSI).
 
The U.S. entrance to the tunnel was concealed beneath the front porch of a home located approximately one-half mile west of the DeConcini Port of Entry. Further inspection revealed the tunnel ran south into Mexico, coming up inside a drainage tunnel that parallels the U.S./Mexico border on International Street.
