Police and school officials assured there was no immediate threat after an anonymous message was discovered on a bathroom stall late Monday morning at Columbia Middle School.

Columbia Police Chief Jason Donjon said today’s date along with mention of an active shooter were found on a stall in the eighth grade boys bathroom shortly before 11:10 a.m. Donjon said police looked at surveillance video as part of its investigation into the matter.

“Police officers responded and will remain on scene as we continue to work in cooperation with school officials to identify the source of the threat,” the Columbia Police Department stated in a Facebook post. “There is no immediate threat. The safety of the school and students remain our priority.”

Columbia Superintendent of Schools Chris Grode confirmed in a notification to school district parents that the incident stemmed from a bathroom stall message.

“District procedures to ensure the safety of our faculty and staff were followed. More information will come as necessary,” Grode said. “Currently, all buildings are secure.”
