Tucson Sector Border Patrol agents from the Douglas Station discovered a collapsed illicit tunnel after a city employee reported a suspicious opening near the Raul Hector Castro Port of Entry Wednesday morning.
Agents responding to the report confirmed the tunnel once extended into the United States approximately 60 yards.
The tunnel is adjacent to a sewer line and had cut through a tunnel previously remediated.
Based on assessments made by the Tucson Sector tunnel team, the tunnel showed no signs of recent use and was collapsed about 25 feet from its opening.
