Sunday

Tucson Sector agents discovered the tunnel west of the Deconcini Port of Entry and only 50 yards east of the tunnel discovered days prior.

Mexico’s Policia Federal subsequently located the tunnel’s entrance in the floor of the existing Grand Avenue Drainage System in Mexico. The tunnel followed the footer of the International Boundary Fence at a depth of about 10 feet, crossed beneath it, and came up approximately 5 feet north of the fence.

Agents discovered the 125th

border tunnel within the

Tucson Sector

U.S. authorities remediated the tunnel on Monday, December 9. This is the 125th tunnel discovered in the Tucson Sector since 1990 and the second discovered this month.

U.S. Border Patrol frequently works with strategic partners to conduct joint operations, and binational cooperation with Mexico plays a vital role in border security. These efforts aim to prevent the movement of illegal contraband or persons across the border.
