Agents assigned to the Special Operations Detachment, working in a remote area west of Tucson late Sept. 28, encountered two Mexican nationals armed with rifles. While attempting to arrest the individuals, one subject ran. When an agent caught up with the subject, an altercation ensued and a second agent had to assist in subduing the subject. One agent suffered a dislocated shoulder during the altercation. Agents also seized four weapons during the encounter.
A few hours later, on Sept. 29, Douglas Border Patrol Station agents encountered two Mexican nationals illegally present in the U.S. As agents were arresting the subjects, one refused to comply and punched an agent in the throat and torso before being subdued.
