Newly released video shows a woman ramming a vehicle carrying federal agents in Chicago on Saturday, according to law enforcement officials. The woman, identified as Marimar Martinez, was armed and was shot by officers during the incident. She later drove herself to a hospital, was treated for her injuries, and was arrested after being discharged. She is currently in FBI custody.

Authorities said another individual, Anthony Ian Santos Ruiz, who was driving a separate vehicle involved in the ramming, was also apprehended.

The confrontation occurred Saturday morning near the intersection of 39th Place and South Kedzie Avenue, when Border Patrol officers were reportedly ambushed by individuals who used their vehicles to trap the agents’ car. After the officers exited their vehicle, one suspect allegedly attempted to strike them with her car, prompting the use of force.

Officials said Martinez was carrying a semi-automatic weapon and has previously been accused of publishing personal information about federal agents online.
