A U.S. Customs and Border Protection officer fired on a woman crossing an international bridge from Mexico after she attempted to run them down while entering Texas.

A 22-year-old woman, a U.S. citizen, was returning to Texas from Reynosa, Mexico, when she attempted to bypass security by driving through the border crossing checkpoint at a high rate of speed. It appears she attempted to run down CBP officers trying to stop her. One of the officers fired a shot from a service-issued shotgun, information obtained by  Breitbart Texas from CBP officials revealed.

The officer fired his weapon after witnessing that his fellow officers’ lives were in danger, the statement said. Other officers in a pursuit vehicle chased the woman as she left the bridge and drove into Texas. At some point during the pursuit, the woman made a quick U-turn in her 2004 Chevy Cavalier and struck the pursuit vehicle head on.

The woman was injured in the crash. She was secured by the CBP officers on the scene and police officers from the McAllen Police Department arrived to arrest her. She was transported to a local hospital for treatment of her injuries. Her condition is not known at this time.

No Customs and Border Protection officers were injured in the initial incident on the bridge. No officers were injured in the crash.

The incident involving the alleged aggravated assault of these federal officers is being investigated by the McAllen Police Department, the CBP Homeland Security Investigations and the CBP Office of Professional Responsibility.

It has not yet been determined why the woman attempted to run the security checkpoint and illegally re-enter the United States. It was also not revealed if the woman had any kind of contraband in her vehicle at the time of the incident.
