Franklin Police report that Jonah Thomas Madison, 18, of Clark Street, was arrested Tuesday at 3:10 p.m.
He was charged with Sept. 22 warrants that accuse him of terrorizing and criminal mischief when he allegedly falsely reported a shooting of two persons to Franklin police.

Not long after that, at about 1:32 p.m., he reportedly called in a bomb threat to the school.
Madison was charged with communicating false information of a planned bombing on school property, terrorizing, criminal mischief and fraudulent impersonation of a law enforcement officer or firefighter.
No bond was set.
