TUCSON, AZ (Tucson News Now) -
An unfinished smuggling tunnel was shut down today in Nogales.
According to a news release from U.S. Customs and Border Protection, Border Patrol agents, working with the Border Enforcement Security Task Force and federal police from Mexico, located the tunnel west of the DeConcini Port of Entry this morning.
The release said Mexican authorities detained one person, who was allegedly digging the tunnel.
The tunnel extended five feet into the United States, but did not have an entrance on the U.S. side of the international border.
The discovery was made during a bi-national patrol of existing infrastructure, looking for vulnerabilities.
