— Raleigh police said Tuesday that they plan to charge an Athens Drive High School student who allegedly shoved a school administrator into a plate-glass window during a lunchtime fight.

Steven Miller, an assistant principal, was taken to a local hospital around noon Tuesday after he was injured while trying to break up the altercation.

He was treated and later released.

Investigators did not identify the student or say what charges might be filed.

Students said there were numerous fights within about 15 minutes and that Miller was trying to break up one of those, near the cafeteria.

Sophomore McKenzie McCarthy said a student grabbed Miller's shoulders and shoved him into the glass.

"To see him just manhandled like that, it was really scary," she said. "It's like something that happened right in front of you, and your principal is harmed, and you're like, 'What are you going to do?'"

Mike Charbonneau, a spokesman for the Wake County Public School System, said school administrators are looking into what started the fights but that none of them appeared to be related.

"Safety and security is the top priority for all of the students in Wake County, and anytime an incident happens, our security staff has procedures and protocols in place," Charbonneau said. "They jump right in to ensure that all students stay safe in the process."

Charbonneau did not say what disciplinary action might be taken against students.
