A man and woman were arrested at Millbrook High School on Monday and charged with beating a 15-year-old male student and trespassing on school grounds.
Jairon Xavier Alston, 19, was arrested at the school after a school resource officer called other officers for help, officials said.
According to an arrest warrant, Alston assaulted another person "by punching him repeatedly while he was on the floor." Police charged Alston with assault and battery and second-degree trespassing on school grounds, both misdemeanors.
At the same time police were making the arrest at the high school at 2201 Spring Forest Road, officers were arresting Ivory Jade Alston, 35, at Millbrook Middle School at 3801 Spring Forest Road.
Ivory Alston also was charged with misdemeanor assault and battery and trespassing at the high school.
The charges did not disclose whether police think they know why the 15-year-old was attacked.
Police said the Alstons were believed to be related, but they could not confirm how. Different addresses for them are listed in arrest records.
Both Alstons were freed on bail and are scheduled to appear in court April 9.
