A Border Patrol agent was injured this week, reportedly attacked by an illegal immigrant with an "extensive" criminal record while on patrol at the southern border, officials said.

The unidentified agent with the Calexico Border Patrol station was near the fence Monday morning when, according to officials, she was attacked by 33-year-old Josue Gomez-Reyes.

The Mexican national is said to have approached the agent, who was inside her marked vehicle, about 8:15 a.m., launching a partial lawnmower blade at the driver’s side of the car.

“Our agent was ambushed while faithfully carrying out her sworn duties as a law enforcement officer by a gang member with a lengthy criminal history here in the United States,” she said.
