INDIANAPOLIS — An Arsenal Technical High School student recorded a teacher losing his temper, yelling and at one point cursing at students.

It happened Tuesday during a second period music class, according to the student’s mother.

She says her son, a freshman at the school, sent her the video which she then shared on social media and with Eyewitness News.

The video is brief but it’s not hard to conclude that the man seen and heard yelling is angry.

In the video, the teacher says to the students, “Nicely to be quiet for nine weeks. I’ve asked you to be quiet for nine (expletive) weeks and you…”

At that moment laughter from some of the students interrupts the teacher’s rant.

The teacher then addresses one student, saying, “Shut up, Trin!”

Off camera, a voice can be heard saying, “Call my mamma, call her.”

The teacher replies, “What? And tell her that I cannot…”

The teacher is interrupted again by a someone saying, “Let me call her and tell her to come up here.”

“I’m looking at the video and I had to watch it a couple of times,” said mom Jerrilyn Bryant. “I’m like, ‘Oh my god, who is he talking to?'”

Bryant said her Trinitee was in the classroom Tuesday and recorded on his cell phone when the teacher started yelling at students. She believes her son is the student the teacher can be seen and heard telling to shut up.

“As a teacher, you’re teaching these children that it’s ok to lose control, it’s ok to cuss someone out,” said Bryant.
