U.S. Border Patrol officials say agents have shot and wounded a man at an immigration checkpoint in southern Arizona after an exchange of gunfire. The agents were not hurt, and have been placed on administrative leave.

According to CCSO they received a call at 3:04 p.m. Wednesday, May 17 from a Tombstone resident, who said her 76-year-old father had left home, possibly heading to Sierra Vista.

BP agents returned fire and shot the man. The driver and sole occupant of the vehicle was shooting out the window at the agents.

The FBI, CBP's Office of Professional Responsibility, the Tombstone Marshal's Office and the Cochise County Sheriff's Department are involved in this ongoing investigation. The woman said he had just left home and she was anxious about his medical condition and the guns and alcohol in his truck, sheriff's spokeswoman Carol Capas said.

The driver was provided medical attention on scene by an EMT Border Patrol Agent and was subsequently flown via helicopter to a Tucson area hospital for advance medical treatment. He remains in custody while he recovers.

A multiagency is investigating the shootout.
