The Georgia man accused of calling in fake bomb threats to Palm Beach County schools and businesses is in a South Florida jail.
Preston McWaters is being held at the Joseph V. Conte Facility in Pompano Beach.
Last week a federal judge set a $250,000 bond for McWaters.
He is scheduled to go to trial next month.
The 25-year-old faces 15 counts related to threats investigators say he made targeting schools, an airport and a business.
