A special education teacher who previously worked at a South Austin elementary school has been accused of biting a student while she was employed there, according to an affidavit from the Austin Police Department.

Officers were dispatched to Cook Elementary School on March 6 where the assistant principal told responding officers that a 9-year-old student was bitten by Courtney Nikole Williams, a special education teacher there at the time.

When officers spoke with Williams, she said she took the student outside of a classroom because she was being disruptive. Once they were in the hallway, she said the student began flailing her arms. Williams said she then took her into the conference room across from the classroom.

She said she was standing behind the student when she said started to push her left arm up. Williams said the student's arm made contact with her nose and mouth area. Williams said at that particular moment she had her mouth open to tell her to stop resisting and that's when she closed her mouth on the victim's arm.

Police said a circle appeared on the victim's upper left bicep. They said the injury broke the victim's skin.

A school counselor who spoke with police said she heard a scream and looked through the conference room door. She said she could hear the student screaming, "You bit me, you bit me."

Based on evidence, police have charged her with injury to a child.

Austin Independent School District confirmed to KVUE Thursday that Williams submitted her resignation letter on April 13.
