UPDATE[6:05 p.m]: Authorities arrested a 14-year-old believed to be behind the threats at North Paulding High School, officials said at a press conference Friday.

ORIGINAL STORY: The threat of a shooting at a metro Atlanta high school kept thousands of students away from the campus Friday, an official said.

Of North Paulding High School’s 2,312 students, only 102 showed up, Paulding County School District spokeswoman Suzanne Wooley told The Atlanta Journal-Constitution.

While principal Mark Crowe described the the threat as “a low-level, non-credible threat” and said operations would continue as normal, he said Thursday absences would be excused and prom attendance requirements would be waived for those who didn’t attend school.

“Parents and families should discuss and make a decision that is right for your family,” Crowe said Thursday in a letter to parents that was posted on social media.

The letter was distributed after officials discovered a threat written on a desk at the Dallas campus. The threat “indicated that there would be a shooting at the school on May 5th,” Crowe said.

There were no incidents at the school Friday, Paulding sheriff’s spokesman Sgt. Ashley Henson said.

“Everything ended up as a normal day minus the students that did not show up,” Henson said. “We had extra deputies there all day and nothing problematic happened

Henson said at least one deputy routinely patrols each high school and middle school in the county every school day. No additional police presence is planned for Monday.

Attendance also was off at two other Paulding schools Friday, Wooley said.

At McClure Middle School, 1,010 students were on campus or at off-campus events, Wooley said. That’s 78 percent of the enrollment. About 75 percent of the students attended at Burnt Hickory Elementary.

While they were not targets of the threat, the schools also received additional police protection Friday, the district said.
