The video, posted on SnapChat, included a threat to "blow up Eastern High School." It was brought to the attention of Alamance County Sheriff's Office investigators on Wednesday.
Nasia Kawan Kimber-McAdoo, 17, of 1the 1300 block of Beaumont Court in Burlington, was charged with one count of making a false report concerning mass violence on educational property, which is a felony.
Investigators said they think McAdoo acted independently of another student who was arrested Wednesday on similar charges. The cases do not appear to be related.
Kimber-McAdoo was released from custody after posting a $25,000 secured bond.
The Sheriff's Office said it did not know whether Kimber-McAdoo was a student at Eastern or any other Alamance County school.
