Atlanta, GA — A Druid Hills High School student was arrested Thursday afternoon and will face charges of aggravated assault and carrying a weapon in a school safety zone, DCSD Police Chief Bradley Gober said during a press conference.

Druid Hills High was placed under a Level 2 lockdown on May 5.

The student’s motive is currently unknown. No weapon discharges or injuries were reported.

Following the press conference, DeKalb County School District spokesperson Donald Porter released a statement saying, “Chief Brad Gober announced that the weapon a student reportedly brought onto the Druid Hills High School campus, prompting a lockdown this morning, has been recovered and secured by the DeKalb County School District police. It was located at approximately 4:30 p.m. in a wooded area near the North DeKalb Mall.”

Gober said that it was only the one student, who led officers to the weapon’s location after being apprehended, according to Porter.

It is unclear if another student was involved in the incident.

At about 12:10 p.m., the lockdown at Druid Hills High was lifted, and regular school operations resumed. The incident is under investigation, according to Porter.

“The lockdown did not result from an active situation,” he said. “Officers with the DeKalb County School District Police Department and the DeKalb County Police Department were on site throughout the lockdown.”

“The lockdown was lifted after a complete school sweep was conducted, and the student was not located on campus,” Porter added. “Additionally, there was an increased police presence through dismissal as an enhanced safety measure.”

Gober said that at about 10:30 a.m. Druid Hills High students went to the principal’s office to notify him that they believed another student in class had a weapon, at which time the principal let the school resource officer and administrative team know about the accusation.

“They immediately followed DeKalb County Schools’ protocols and locked the school down,” Gober said. “They went on a level two lockdown and went on a search for the alleged student. At this time, other school resource officers from surrounding schools were in route to the school. They got to the school and did a search. They went from classroom to classroom looking for the student that allegedly had the weapon. Once they cleared the building, they heard that the student may be in the surrounding area, which is the wood line or either the park. DeKalb County Police and Emory University Police assisted us in these searches.”

Police searched the school grounds this morning and were unable to find the student. The student was found on Emory University’s campus and was arrested by Emory Police shortly before the press conference, which began at 4 p.m.

The news of the lockdown followed an initial announcement by Emory University that an “active shooter” was on the university’s campus. The high school is near Emory. The university later updated the post saying there was not an active shooter on campus.

Emory University has given the all clear to its campus community, the university tweeted.

“Emory Alert: An all clear has been issued for Emory University,” the tweet said, after telling staff and students to shelter in place for about two hours after DHHS lifted its lockdown.

According to a source who emailed Decaturish, DHHS was under a level 2 lockdown. Students were locked in their classrooms and police were going through the classrooms looking for someone. The source noted that the building’s HVAC does not work.

“The campus is wide open, with several exterior doors lacking working locks and multiple cameras being nonfunctional,” the source said in the email.

Principal Mark Joyner also sent a notification to parents about the situation, stating the school was “under a Level 2 lockdown due to a report that an unauthorized individual was seen on campus,” she wrote.

DeKalb Schools Public Safety Department assisted to make sure that all individuals on campus were authorized to be there, Joyner wrote.
