Chickamauga Elementary School had its day disrupted Monday when two high school students sprayed pepper spray in the area, Chickamauga Schools Superintendent Melody Day has reported in a letter to parents.
She wrote that an odor was coming from the copier room and some teachers and students experienced coughing.
A maintenance technician was dispatched to the school and the students were evacuated to the gym as a safety measure, Day said.
But she said in her letter it was determined that two high school students had sprayed their pepper spray containers to check them.
She said it reflected a lack of judgment and that the high school administration will address this discipline problem.
Students at the elementary school returned to their classes about an hour after the disruption.
