(AP) — A Kansas City mother has been charged with beating up her child’s kindergarten teacher.

Jackson County prosecutors filed a third-degree assault charge Monday against 25-year-old Simone Baker. Police said in a news release that Baker isn’t currently in custody. No attorney is listed for her in online court records.

Police reports say the mother pulled the teacher out of her chair by the hair, punched her in the face and slammed her head against a file cabinet in September at Truman Elementary School in the Hickman Mills School District.

Police reports say the mother was upset because her 6-year-old son had blamed his teacher for a scratch on his neck. But a district official has said that the boy told administrators and police that the teacher hadn’t hurt him.
