Border Patrols agents Thursday discovered a recently dug tunnel that crossed the border and ended in downtown Nogales, Ariz.

Agents found the tunnel after arresting several illegal immigrants who they believed had come through a tunnel in downtown Nogales, according to a statement released by U.S. Border Patrol. Agents overheard voices coming from a nearby steel water grate while patrolling the area near West Street and Interstate 19. Agents removed the grate and entered the drainage system, causing several men to flee south through the tunnel toward Mexico.

The tunnel was dug to get around security obstacles placed in the drainage system, according to the Border Patrol statement. It crossed a water grate and appeared to head north across interstate 19.
