Gainesville High School was back to normal operations Wednesday afternoon following investigation of a potential bomb threat, police said.

“Out of an abundance of caution, we’ve done sweeps of the campus to ensure safety of all students and employees,” Gainesville Police Sgt. Kevin Holbrook said. 

Police are working with the Hall County Sheriff’s Office and school officials, as the case is still under investigation.

Gainesville Police and Hall County Sheriff’s Office deputies responded to the high school to investigate a bomb threat that was found written on a wall, according to spokeswoman Cpl. Jessica Van.

“We are in the process of a full accountability check on our student body and ensuring that they eat,” Gainesville High Principal Jamie Green wrote in a statement before 2 p.m. Wednesday.
