Wild video shows the moment a fight erupted Wednesday between a school safety monitor and a teacher at a Pennsylvania High School.

The teacher was seen trying to fend off the security agent with punches before he was taken down on a classroom floor at Harrisburg High School, according to WHTM-TV.

The men then wrestled as other teachers, safety agents and a student tried to break up the brawl.

It began after the security monitor entered the class and confronted the teacher about a personal matter, School District of Harrisburg Superintendent Eric Turman said during a press conference.

The two school employees were reportedly placed on leave while officials investigated the fight, which was an “isolated” incident, according to the administrator.

“I want to make it clear that this incident is entirely unacceptable,” Turman said.

“This is highly unusual and is not at all representative of our faculty and staff who take responsibility as role models for our students very seriously.” 

In a letter to students and parents, the superintendent reportedly apologized for the ” impact this incident may have has on students who look to our staff as trusted adults.”
