Treutlen County's K through 12 school was locked down Thursday afternoon, said Sheriff Tommy Corbin.

School officials found a .22 caliber rifle in a student's vehicle. A lock-down was initiated because of school policy, and the sheriff's office was called to search. Corbin says deputies used drug- and bomb-sniffing dogs during the lock-down but found nothing inside the school.

A small amount of marijuana was discovered in the student's vehicle.
The student, a juvenile whose name was not released, was arrested and charged with possession of a firearm on school grounds and possession of marijuana on school grounds.
