The Border Patrol is searching for a Mexican man they say assaulted an agent over the weekend on the Tohono O'odham Indian Reservation west of Tucson.
The agent assigned to the agency's Ajo station was assaulted while responding to a call Saturday near the community of Gu Vo.
The unidentified agent suffered face cuts and a broken orbital bone and required 22 stitches, the Border Patrol said in a news release.
The agent was taken by helicopter to a Tucson hospital and has since been released.
The Border Patrol says the FBI is investigating the assault.
A person of interest in the attack has been identified.
