SPRINGFIELD, Ill. (WCIA) — The Illinois State Police has arrested two teenagers for threats of violence at Pana High School.

According to a press release, Pana High School officials found two threatening messages earlier this week in bathroom stalls, which they reported to law enforcement. State Police said the notes were found on two consecutive days and were separate instances. After an investigation, State Police identified two teenagers believed to be responsible for the threats.

These threats come only a month after another teenager was arrested for posting a threat toward schools in Pana on Snapchat.

Christian County State’s Attorney Wes Poggenpohl approved one count of disorderly conduct, threat of violence, a Class 4 felony, for each teenager.
