Georgia high school teacher Jesse Randal Davidson, 53 (pictured), was taken into custody after he fired at least one shot and barricaded himself in a classroom on Wednesday morning

Police officers responded Wednesday to a Georgia high school after reports of shots fired and a teacher barricaded in a classroom, authorities said.

Police in Dalton tweeted that the teacher was in custody and no children were ever in danger.

During an afternoon press conference, authorities identified the teacher as Jesse Randal Davidson, 53, who also worked as an announcer during the school's football games.

Dalton police said Davidson has been charged with aggravated assault, carrying a weapon on school grounds, making terroristic threats, reckless conduct, possession of a gun during commission of a crime, and disrupting public school.

Davidson, who teaches social studies and has been with the school since 2004, allegedly barricaded himself inside of a classroom, not allowing students to enter. When the principal came to attempt to unlock the door, a shot was fired.

Students shared videos to Snapchat of fellow students running through the hallways of Dalton High School and being escorted out of the building by police.

A student apparently suffered an ankle injury running inside the school as the building was evacuated.

Police say the social studies teacher locked himself in a classroom and wouldn't allow students in and, when the principal unlocked the door, he allegedly fired a shot

Frightening and all too familiar scene unfolded Wednesday at the high school as police scrambled to the scene and students ran for their lives. But this time, a teacher was arrested in the incident

The incident was reported just after 11.15am on the Dalton Police Department's Twitter account

The incident was reported just after 11.15am on theDalton Police Department's Twitter account, reporting that 'shot or shots' had been fired at the high school on the department's official Twitter account.

Minutes later, DPD added that the armed suspect was barricaded inside a classroom at the school and urged parents not to come to the school.

Davidson was barricaded inside the classroom for about 30 minutes before he was taken into custody.

Police say a 'threatening' note was found last week at the high school.

It wasn't immediately clear whether the note was related to the shooting Wednesday.

Police say the note was found February 21, and mentioned a threat against the school the following day.

Assistant Police Chief Cliff Cason said in a statement at the time that officers planned an increased presence at the city's schools in response to the note.

Police have not said why Davidson fired the gun.

A mother of one of the students says she was terrified as her daughter texted her while hiding inside her darkened classroom as police responded to reports of gunfire inside the school.

Annmarie Jacobs says her daughter Emma texted that her teacher had turned the lights off and told the students to sit in a corner.

Then, in an act that brought home the danger of the situation, her daughter texted, 'omg she's putting desk in front of the door.'

Jacobs said she was about 100 miles away from Dalton High School and driving through Tennessee when she got the texts, and pulled over on the roadside, shaking.

Students were evacuated to the Dalton Convention Center, where parents were instructed to pick up their children.

The incident happened two weeks after a school shooting in Florida left 17 students and faculty dead and put the country on edge.

The high school's website says it has 2,000 students. Dalton is about 90 miles north of Atlanta.

President Trump suggested arming teachers in the wake of a deadly school shooting earlier this month in Parkland, Florida, where 19-year-old Nikolas Cruz stormed his former high school and killed 17 people with an AR-15 semiautomatic rifle.

The president proposed a controversial bill last Wednesday to provide as many as 20 percent of teachers with concealed and carry permits after meeting with students from Marjory Stoneman High School.

He beefed up his proposal saying educators who chose to have weapons in their classroom would receive a 'yearly bonus'.

Neither Trump nor the White House has said who would pay to train them, but the decision would be 'up to states'.

He doubled down on the proposal on Saturday, stating in a tweet: 'Armed Educators (and trusted people who work within a school) lover our students and will protect them.

'Very smart people. Must be firearms adept & have annual training. Should get yearly bonus. Shootings will not happen again - a big & very inexpensive deterrent. Up to States.'
