Authorities say 66-year-old William Adams phoned in a threat early Wednesday morning that prompted three schools in Fulton County, and a school in Sharp County to evacuate.
No explosives were found.
Authorities traced the call back to Adams, and after a formal interview determined there was enough probable cause to arrest him.
Adams was arrested and charged with falsely communicating a terroristic threat, which is a class B felony.
He is currently in the Fulton County Jail on $200,000 bond.
