Various US media outlets are reporting that a teacher fired a gun in Dalton High School in Georgia in the US. Time.com states that the teacher barricaded himself into a classroom before firing a gun as a 'warning shot'. The social studies teacher had a 45-minute standoff with officers, before the policemen were able to make their way into the school.

Police say a teacher has been taken into custody after a security incident at Dalton High School in Dalton, Georgia, involving a person who was barricaded in a classroom: "no children hurt, no children in danger."

No students were seriously injured in the incident, except for a teenage girl who sprained her ankle while running from the gunfire. Dalton police spokesman Bruce Frazier said that the teacher, Jesse Davidson, 53, also serves as the play-by-play announcer for the high school’s football team. Many of the school's students are taking to social media to protest against gun violence. It comes after 17 students were killed in a Florida high school earlier this month.

@nra my favorite teacher at Dalton high school just blockaded his door and proceeded to shoot. We had to run out The back of the school in the rain. Students were being trampled and screaming. I dare you to tell me arming teachers will make us safe.

Shots were fired today at Dalton High School in Dalton, Georgia. No one was hurt, and the school was evacuated. The suspect barricaded himself in a room before being arrested. He was a teacher. Can we stop talking about arming teachers and bringing more guns into schools?
