Video of students threatening, bullying teacher surfaces online

The footage is difficult to watch.

A video of high school students bullying and harassing their teacher has surfaced online.

In the clip, several students can be seen shouting and throwing things at the teacher, telling her to “sit your a** down” and threatening her with a chair while his peers can be heard egging him on.

“What I say something I mean it. Now ask me what my name is again,” a male student says as he tries to make his way toward the teacher while his classmates hold him back – all while laughing hysterically.

The male student later picks up a chair and desk, holding it above her head and threatening to “smack her a** with a whole bag of M&Ms.”

The video shows the teacher somehow remaining calm throughout. At one point, she tells the student recording the video, “Young lady I’m going to have to ask you to have a seat.”

Still seated at her desk, the teacher politely tells the student who is throwing things at her to get rid of “whatever you’re throwing.”

The incident reportedly took place at Chicago Vocational Career Academy. The teacher is referred to as “Mrs. Cox” throughout the clip.
