One individual is in critical condition following a Border Patrol-involved shooting in Pima County, Arizona, on Tuesday morning.  

The Pima County Sheriff’s Department was called into the federal investigation on Tuesday, a spokesperson for the department told The Daily Signal. 

Local NBC News affiliate News 4 Tucson reports that the same individual who was wounded was also in custody, and received immediate medical attention before being transferred to a local hospital.  

“The FBI office out of Phoenix gave us a call to do our own parallel investigation into an officer’s use of force,” the spokesperson added.  

The FBI said it was investigating an alleged assault on a federal officer near the town of Arivaca in Arizona and that a subject was taken into custody, adding that the investigation remains ongoing. 

Arivaca is about 10 miles from the border of Mexico, 70 miles south of Tucson. It is known as a busy area for illegal alien border crossings, according to Reuters.
