Authorities say that an elementary school student used an empty BB gun to threaten other students on Friday.

The student is a 3rd grader at Brunson-Dargan Elementary School, said Audrey Childers, Public Information Officer for Darlington County Schools.

Childers said the incident happened at a bus stop and on the school bus. She said that the gun was not loaded.

“The students reported the incident after they arrived at school. The School Resource Officer was immediately notified and an investigation is ongoing,” Childers said in a press release.

“The school district intends to pursue this to the full extent of the law,” she added.

BB-guns, pellet guns, and air guns are among the items prohibited at all Darlington County School District schools.

“All schools in the school district take safety very seriously and work closely with local law enforcement to keep our students, staff, and schools safe,” Childers said.
