The 16-year-old student has not been identified because of her age, but she was arrested on Tuesday after an investigation and charged with second-degree assault, a Class D felony.
WCBS-TV reported that video of the attack was posted to social media and showed a young woman striking a teacher numerous times as she was on the floor behind her desk. That video was posted to the Facebook page of Yonkers Newswire.
The district told WCBS that security officers responded to the incident quickly and intervened. They did not indicate whether the teacher was seriously hurt.
The student also faces expulsion over the incident after a superintendent's hearing.
