NASHVILLE, Tenn. (WKRN) – A video making the rounds on the Internet shows a teacher being punched in the face by a student at one of Nashville’s largest high schools.

The incident, first posted to YouTube, happened Tuesday morning at Hunters Lane High School in North Nashville.

In the video, captured by a cell phone, the student is seen punching the teacher in the face. You can also see the teacher’s head hit the floor.

The student then straddles the teacher and continues punching him until someone pulls him off.

Metro police identified the teacher as a 24-year-old male but News 2 is not identifying him.

Investigators said the teacher was directing traffic in the hallway when the attack occurred. He reportedly told the student to stop because he was going the wrong way and that’s when the student punched him, according to police.

Metro police said he did nothing to provoke the attack.

The 17 year-old student was arrested and charged Tuesday with aggravated assault and resisting arrest.

Metro Schools spokesman Joe Bass confirmed the assault did in fact happen at Hunters Lane High School.

In a statement to News 2, Bass said, “The student involved was disciplined appropriately, though Federal privacy laws bar us from publicly stating what that discipline was. Response from school staff was swift, with another faculty member intervening very quickly. The School Resource Officer and other Metro Police officers were involved, and we thank them for their assistance. We take the safety of our students and staff very seriously, and violence against employees, no matter who is the perpetrator, will not be tolerated in any way.”

Bass also told News 2 that an assault on a teacher is considered a zero tolerance offense.

News 2 has learned it’s not the first time Metro police have been called to Hunters Lane High School.

Since August, there have been 30 arrests which have involved three adults, 19 juveniles, six juvenile citations and two juveniles arrested on outstanding warrants.

The charges include 14 assaults, three disorderly conducts, three drug charges, two weapon violations and 19 other charges.
