The student told Frederick County sheriffs deputies that he had brought the gun to school Tuesday for protection, saying he was afraid for his own safety after a fight on campus the previous day.
School officials say the teen did not threaten anyone with the firearm but did show it to fellow classmates. Some of those students alerted the assistant principal to the situation.
When the teen was taken out of class and searched, deputies say they found the gun. The student was turned over to Maryland's Department of Juvenile Justice and now faces four charges related to bringing a concealed gun on school property.
