The Madison County State's Attorney Office charged an Alton teen Monday with falsely reporting bomb threats to Alton-area schools.

In a press release issued by the Alton Police Department, officials said Kiyree D. Collins, 19, of Alton, called both the Alton High School and Alton Middle School in September claiming a bomb was located at both school campuses.

Both schools evacuated their students and later canceled classes for the day because of the threats made. As the day progressed, authorities found there were no explosive devices on either school campus.

In coalition with the Madison County Sheriff's Office, the Alton Police Department were able to identify Collins as the suspect who falsified the bomb threat claims.

The Madison County State's Attorney's Office charged Collins with two counts of Disorderly Conduct.

Collins was put into custody at the Alton Jail. His bail was set at $200,000.

"We take any threat very seriously and I am proud of the joint efforts by both police agencies involved in this investigation," said Alton Chief of Police Jason Simmons in a statement. "The Alton School District students, staff, and parents did an excellent job maintaining order and calm in the wake of what is a scary situation when someone makes such a disturbing threat."
