Georgia Teacher Arrested After Shot Fired in Empty Classroom

A social studies teacher barricaded himself inside a classroom at a Georgia high school on Wednesday and fired a single shot from a handgun, authorities said.

No students were in the classroom at the time, and the only injury reported was a student who hurt her ankle running when Dalton High School was evacuated, the Associated Press reports.

The teacher, Jesse Randal Davidson, was taken into custody without incident after a 30- to 45-minute standoff with officers, Dalton police spokesman Bruce Frazier said. Davidson, 53, serves as the play-by-play announcer for the high school's football team, police said in a tweet .

Police didn't immediately say why Davidson reportedly fired the gun, but noted that he aimed away from anyone into an exterior window as the principal tried to unlock the classroom door. After the gunshot, the school was immediately placed on lockdown.
