A 14-year-old St. Rose boy was taken into custody Tuesday on one count of terrorizing after he allegedly threatened online to shoot students at a North Carolina high school, the St. Charles Parish Sheriff’s Office said Wednesday.

The boy, who was not named because of his age, admitted threatening particular students in an Internet chat room to gauge the reaction of the students he was talking with, St. Charles Parish Sheriff Greg Champagne said in a news release. “The juvenile obtained the students’ names from a social media account to make them think the threat was real,” the release said.

Champagne’s office, with help from officials in the Cumberland County, N.C., Sheriff’s Office, started investigating the threats on Oct. 6. The boy was arrested two days later. He was being held Wednesday at Assumption Parish’s youth detention center on a $100,000 bond.
