A juvenile was arrested on the Neshoba Central High School campus Wednesday morning on multiple charges following an altercation with a student, a teacher and a principal shortly before classes started.

The juvenile, who is not enrolled in the school, posed as a student and boarded a Neshoba Central bus that morning, Sheriff Tommy Waddell said.

County Superintendent of Education Tommy Dearing said the juvenile was waiting with a student at a bus stop and told the driver he spent the night at his house.

"He had the aid of another student," Dearing said.

The juvenile arrived on the high school campus and proceeded to the school gym where other students were being held until classes began, he said.

The juvenile then got into an altercation with another student, which was soon broken up by nearby teachers, Dearing said.

No one was seriously injured, the Sheriff said.

The juvenile and the student involved in the altercation were escorted to the main office. While being questioned, the juvenile ran from the office and was quickly apprehended by Sheriff's deputies and principals, Dearing said.

During the investigation, officers viewed a video on a cell phone which showed the juvenile with a firearm in a vehicle parked on the Neshoba Central campus a day earlier on Tuesday, Waddell said.

"It was a long gun not a handgun," he said.

The juvenile was charged with possession of a firearm on a school campus, possession of ammunition on a school campus, one count of assault on a principal, one count of assault on a school teacher, one count of assault on a minor, resisting arrest by fleeing, providing false information to a police officer, trespassing on the school campus and obstructing operation of a school bus.

After being charged, the juvenile was taken to the Scott County Detention Center.

The county school district has three certified and armed officers on campus daily.

Dearing said all the officers and school personnel involved in the incident acted appropriately according to school policy.
