Columbus police have made another arrest of a juvenile threatening Columbus East High School.

Lt. Matt Harris says that a fire alarm at the school was accidentally set off at about 8 a.m. this morning while students were moving items. When students evacuated, a former student who is still a juvenile, sent a threatening message on social media.

The school began lockout preparations but the former student was found off of school property and arrested. The juvenile has been taken to the Bartholomew County Youth Services Center and is facing a preliminary charge of intimidation, Harris said.
