Candler County sheriff's deputies arrested a Metter Middle School student on Tuesday for making threats of harm.
The 13-year-old boy "threatened several students," said Candler County sheriff's Capt. Justin Wells.
School officials notified the school resource officer of the incident, and the SRO "took swift action and opened an investigation" that led to the teen being charged with several counts of terroristic threats, he said.
The arrest follows two in Bulloch County last week.
On Thursday, a Statesboro High School female juvenile student was arrested for false report of a crime after telling administrators that she saw a threat on social media and showed it to her mother. Her mother denied any knowledge of the incident, and the girl admitted to making it up, reports stated.
Late Friday night, a Southeast Bulloch High School 16-year-old female student was arrested after reports of her making threats against other students. She was charged with terroristic threats and acts and disrupting a public school.
Similar threats and rumors of possible threats have been rampant across the Southeast region since the Feb. 14 Parkland, Florida, school shooting that left 17 dead.
"Our office takes all threats seriously," Wells said. "We will take appropriate action. We sincerely appreciate those who reported this activity. We remind everyone to report suspicious activity."
Candler County Sheriff John Miles said the boy, charged with several felony counts of terroristic threats, will be detained in a juvenile facility.
