NOGALES, Ariz. -- Tucson Sector Border Patrol agents discovered an illicit tunnel that came to an abrupt stop at the concrete barrier installed to shut down a previous cross-border tunnel located earlier this year.
Nogales Station agents, working with the Nogales International Liaison Unit and Mexican law enforcement, discovered the incomplete cross-border tunnel on March 13, while conducting a routine tunnel sweep.
After observing cinder blocks with fresh mortar within the drainage channel, agents and Mexican federal authorities discovered a 16 by 16 inch tunnel west of the DeConcini Port of Entry leading towards the United States. The tunnel measured approximately 25 feet in length with only six and a half feet extending into the U.S.
Agents will continue to monitor and inspect the incomplete tunnel until remediation is complete.
Tucson Sector's Border Patrol continues to work closely with strategic partners in Mexico to detect tunnels during construction, and to prevent the movement of illegal contraband or persons across the border.
