LEBANON, Tenn. (WKRN) — After investigating a “shots fired” call at Lebanon High School Wednesday afternoon, authorities reportedly determined the noise was not from a threat, but instead what they called “foolish behavior.”

Deputies with the Wilson County Sheriff’s Office were reportedly dispatched to the high school around 1:30 p.m. alongside officers from the Lebanon Police Department. According to the sheriff’s office, someone had reported what sounded like gunshots inside the building.

However, dispatchers quickly were able to confirm through a school resource officer that the noise heard within the school was from students setting off fireworks inside a bathroom, police reported.

The incident was still under investigation Wednesday afternoon. In a social media post regarding the incident, the sheriff’s office said it is “committed in providing our schools with a safe environment and foolish behavior will not be tolerated.”

Wilson County Schools Spokesperson Bart Barker also issued a video statement on Twitter, which can be viewed here.
