Fletcher is already in jail on aggravated robbery charges, stemming from the robbery earlier this month of a Mickey Mart smoke shop, which came less than an hour after the bomb threat.
An Ottawa County grand jury indicted him on one count each of inducing panic and disrupting public service.
Fletcher and his pastor met with Port Clinton police two weeks ago when he admitted to his role in the robbery. He said a friend called in the bomb threat, and he told police the intent was to divert law enforcement attention to the bomb threat.
Fletcher allegedly robbed the smoke shop of about $600 and two cartons of cigarettes.
