NOGALES, Ariz. (AP) - U.S. authorities have unearthed an unfinished border tunnel near Nogales, Ariz., making it the fourth tunnel found in a week.
Immigration and Customs Enforcement spokeswoman Amber Cargile says authorities found the incomplete tunnel on Friday and that it didn't appear to be in use.
Authorities believe the tunnel's aim was to smuggle drugs into the U.S.
Earlier this week, federal officials found three sophisticated drug-smuggling tunnels equipped with lighting and ventilation.
Two were found in the San Diego-Tijuana area, and another was found in a vacant strip mall storefront in the southwestern Arizona city of San Luis.
Cargile says the investigation into the Nogales tunnel is ongoing. No arrests have been made.
