Customs and Border Protection officers and a U.S. Border Patrol agent were involved in a shooting while working at the Port of Nogales Mariposa Crossing.
According to CBP, initial reports indicated a subject attempted to evade Border Patrol agents while driving south through the port around 2 p.m.
The subject swerved his vehicle in an apparent attempt to hit officers working at the port.
Office of Field Operations and Border Patrol agents fired at the driver. He sustained multiple gunshot wounds and was airlifted to a Tucson area hospital.
A passenger in the vehicle sustained non-life-threatening injuries and is currently in custody.
No law enforcement agents have been injured.
Authorities say Border Patrol agents investigating smuggling activities west of the port became suspicious of a Dodge pickup truck and attempted to follow the vehicle before it sped away toward the port.
As agents arrived at the port, they saw the truck stopped in traffic bound for Mexico. CBP says as the truck's driver saw officers approaching him on foot, he accelerated toward them. The officers then drew their weapons and fired.
CBP says the driver, a 26-year-old Mexican national male sustained multiple gunshot wounds but is in stable condition at Banner University Medical Center.
A 16-year-old male passenger sustained non life-threatening injuries and is currently in Border Patrol custody pending further disposition.
The Port of Nogales, Maripoa Crossing has returned to normal conditions.
The FBI, CBP's Office of Professional Responsibility, and U.S. Immigration and Customs Enforcement's Homeland Security Investigations are jointly investigating the incident.
CBP says the U.S. Border Patrol and Office of Field Operations are cooperating with the investigation.
