A woman was injured in a shooting involving federal agents on Chicago's Southwest Side on Saturday morning, the Department of Homeland Security said in a statement.
DHS said its officers were patrolling in the area of 39th Street and South Kedzie Avenue in the city's Brighton Park neighborhood when they were rammed by vehicles and "boxed in" by 10 vehicles.
One of the drivers involved in the car-ramming was armed with a semi-automatic weapon, DHS said, and officers fired "defensive shots."
The allegedly armed woman, a U.S. citizen, was injured and took herself to the hospital for treatment, DHS said.
DHS also said the woman is accused of doxing agents and using vulgar language toward them online.
No officers were injured.
"Pritzker's Chicago Police Department is leaving the shooting scene and refuses to assist us in securing the area. There is a growing crowd and we are deploying special operations to control the scene," DHS said.
