A 16-year-old Youngtown boy was arrested Tuesday on suspicion of bringing a loaded gun to school and making threats.
The student is suspected of having the gun on both a school bus and the Dysart High School campus.
Deputies learned of the suspect after performing a wellness check on a 14-year-old student, who was absent from school. That boy's mother told police her son was threatened by the 16-year-old at a bus stop.
The suspect was contacted by deputies and found to have a loaded .25-caliber pistol in his possession.
The suspect was arrested on four felony charges.
