CLEVELAND: Prosecutors have added five more counts against an Ohio man suspected in dozens of bomb threats made to courthouses and other public buildings in five states.

The FBI arrested 39-year-old Lonny Bristow of Mansfield last week on one bomb threat count and says that prosecutors have added five more.

The additional counts were detailed in a court filing which usually signals a pending plea deal. There was no immediate comment from Bristow’s public defender.

The FBI said Bristow was arrested in the investigation of bomb threats made in November and December to courthouses and public buildings in Nebraska, Washington, Oregon, Tennessee and Mississippi.

The FBI said it traced numerous bomb threats to prepaid phone cards purchased at a Wal-Mart in Upper Sandusky, about 40 miles west of Mansfield.
