A Marietta police officer sustained minor injuries Wednesday afternoon when he was attacked by two students while breaking up a lunchroom fight at Marietta High School, a police spokesman said.

Marietta police spokesman David Baldwin told the AJC that six students, all juveniles, were involved in the fight, which happened around 12:15 p.m. at the school on Whitlock Avenue.

“Administrators were already there, and they quickly broke it up,” Baldwin said.

“The school resource officer responded and as he got there, one of the kids was getting kind of confrontational with one of the administrators and he pulled that kid off the administrator,” Baldwin said. “As he was dealing with him, that kid’s brother jumped the officer from behind and started punching on him.”

The first brother then jumped on the officer as well, Baldwin said.

“Fortunately, it was all over as quickly as it started, because the other administrators and coaches that were there intervened and pulled the kids off,” Baldwin said.

The officer, a regular Marietta police officer assigned to the school, was taken to Wellstar Kennestone Hospital for treatment of “bumps and bruises,” Baldwin said.

The two brothers were taken into custody, charged with obstruction and battery on a police officer, and were transported to a youth detention center.

Baldwin did not know what sparked the initial fight. He said the other students involved in the fight would face school disciplinary action.

In an automated phone message to parents that went out Wednesday afternoon, Principal Leigh Colburn said no weapons were involved, no one was seriously injured and no classes were disrupted in the incident, which occurred during the second of two lunch periods.

Administrators and the police officer assigned to the school quickly broke up the fight, she said.

Two students –- apparently those who allegedly attacked the police officer –- "are no longer on our campus," Colburn said. She said they would face "consequences" outside the school system.
