AUSTIN (KXAN) — An Austin police officer was assaulted Monday in the intersection of 10th Street and Red River Street.

Two officers were leaving Municipal Court in their police vehicle and stopped at a stop sign when Sarah Pierce, 22, shouted, “What are you looking at?”

The officer driving began to roll up her window, responding, “I’m not looking at you.” According to a police affidavit, Pierce approached the vehicle and began pounding on the window and screaming.

The officer, who was wearing plain clothes with her police badge displayed on her belt, exited the vehicle and identified herself as an officer. Police say Pierce flailed her arms and then kicked the officer in the stomach with what was described as a “Karate Kid Crane Kick.”

The other officer was able to grab Pierce and pull her to the ground.

When put in the backseat of the police vehicle, Pierce said she was just having a “bad day” and was upset the officer was looking at her.

The officer chose not to seek medical treatment. Pierce was charged with assault on a public servant, a third degree felony, as well as resisting arrest.
