Online rumors of a possible shooting at Northside High School are untrue, according to Columbus Police and Muscogee County School District officials.

"Nothing has happened. It's been quiet all day," said Columbus Police Lt. Mark D. Starling. "The school security has been on top of it ever since this Tweet came out or however it was publicized. We put four additional officers up there for the duration of today’s school time." Starling said the rumors were that there was going to be retaliation for an incident that happened at the school. "That's all I know," Starling said. "I don’t know what was said in the Tweet."

The rumors prompted calls to 911.

"I think some people called 911 asking about had we heard there was going to be a shooting up there at Northside High School," Starling said.

Keith Seifert, the district's director of secondary education, said he was at the school earlier today.

"The day is running as normal," he said. "... Parents are going to be concerned, and you have to take each situation seriously, and I know the school district is taking that seriously."

Valerie Fuller, the district's director of communications, said Northside principal James Wilson made a recorded telephone call to Northside parents to settle fears. She also said there have been no reports of arrests or disciplinary action taken against anyone linked to starting the rumors.

Wilson couldn't be reached for comment.
