NOGALES, Ariz. - Agents with the U.S. Border Patrol found another cross-border tunnel running under Nogales, Arizona, on Sunday. Four days earlier, U.S. agents found an incomplete tunnel about 50 yards away.
The tunnel discovered on Sunday was west of the Deconcini Port of Entry, authorities said. The opening was about 5 feet north of the International Boundary Fence.
The tunnel crossed under the border fence about 10 feet down, authorities said.
Mexico's federal police tracked down the entrance to the tunnel in the floor of the Grand Avenue Drainage System in Mexico.
The Border Patrol filled in the tunnel on Monday.
This was the 125th tunnel discovered in the Tucson Sector since 1990, U.S. Customs and Border Protection said in a news release.
In August 2018, federal agents found a drug-smuggling tunnel that connected a house in Mexico to an abandoned KFC restaurant in Arizona.
