The video shows the teen suspect, Larrianna Jackson, standing over the teacher at her desk, before suddenly unleashing a flurry of blows to her head, knocking her out of her seat.
"She was just talking to the student about a grade, and the child was just explaining her side, and then all of a sudden she was attacked," St. Tammany Parish Public Schools Superintendent Frank Jabbia said.
Jackson was arrested and charged with Battery of School Teacher, a felony. She was transported to St Tammany Parish Jail to await prosecution.
In a Facebook post, Covington PD said it was investigating if the attack was part of the infamous TikTok "Smack a teacher" challenge.
"Officers learned that this violent attack by Jackson, may have been prompted by a viral social media application known as Tik-Tok," it said. "Evidently users on the app have deemed it to be a challenge to damage school property and attack teachers. The Covington Police Department would like to remind everyone that anyone who participates in such a challenge will be booked accordingly."
