Colleton County Sheriff's deputies arrested a 19-year-old student who allegedly threatened to "shoot up" his high school.
Colleton County High School administrators pulled Steven Anthony Jones from class Friday after students reported he told them about the threat of violence Thursday.
School officials and deputies interviewed several people who confirmed the allegations. Jones admitted to making the statement on more than one occasion, authorities said.
"Investigators believe that the information divulged from interviews showed that Jones posed a 'credible' threat to the safety of other students and staff members at CCHS, as well as himself," the Sheriff's Office said in a news release.
Jones, of Blueberry Court in Walterboro, is charged with disturbing schools. Authorities are continuing to investigate.
The Colleton County incident is the latest amid a wave of threats aimed at schools across the state. Administrators and law enforcement have been on heightened awareness following last week's school shooting in Parkland, Fla., that killed 17 people and injured at least 14 others.
Suspects in school threats can be charged with communicating a threat or disturbing schools, both of which carries less severe penalties than a law proposed this week. The legislation would make threatening violence against a school a misdemeanor that carries up to three years in prison and fines up to $3,000.
