Several American flags were burned about 2 a.m. Monday morning at the entrance to St. James High School in the Socastee area, according to Lt. Robert Kegler, with Horry County police.
The flags were discovered when security arrived for the school day at 6:20 a.m.
Officials reviewed surveillance videos from the school, and the suspect was seen doing things that caused concern to law enforcement officials, Kegler said.
The school was locked down at 8:30 a.m. as a precaution. A telephone message was sent to all parents.
The Horry County Police Department's Bomb Squad was called to the scene and the school was evacuated. Horry County police arson detectives and Horry County fire investigators were also called to the on scene.
After several hours, the students were bussed from St. James High School to St. James Middle School.
Parents of the high school students are being allowed to pick their kids up from St. James Middle School, according to Teal Britton with Horry County Schools. Parents on scene tell us the process is moving slowly.
Britton is asking parents to have patience with the dismissal process, because they have students from two schools on one property.
No students are allowed on the high school property. Students who drove themselves to the high school are not allowed to get their vehicles yet, but parents can pick them up at the middle school.
