A substitute teacher was arrested after police say he perpetuated and recorded fights involving students in his classroom.

Ettson Arreola was teaching at Syringa Middle School in Caldwell on Thursday when two fights broke out between students in Arreola’s classroom.

Both fights — one involving two male students and one involving two female students — were encouraged by Arreola, police said. Additionally, Arreola recorded the fights on video, which was later shared on social media and brought to the attention of Caldwell Police Department School Resource Officers, according to a Caldwell Police Department press release.

Arreola has been charged with four counts of misdemeanor injury to a child; four counts of misdemeanor violation of juvenile corrections act, encouraging a minor to fight; and one count of misdemeanor inciting a riot.

“The preliminary investigation revealed that Arreola set a timer and encouraged the students to fight for 10 seconds, while he recorded it,” the release said. “Fortunately, the students who were involved were not injured.”

Arreola has also been barred from contacting the students involved or any student in the Caldwell School District.

“The Caldwell School District has zero tolerance for this type of behavior,” Caldwell School District Superintendent Shalene French said in the release. “The personal safety and welfare of each child is of paramount concern to the district. The district has taken immediate steps to ensure the safety of all students. We are providing support for the students involved and are actively cooperating with law enforcement.”
