An Ohio man who threatened to blow up several Cincinnati-area landmarks has been sentenced to a year and a half in prison.

Frederick Purvis, of Hamilton, was sentenced Wednesday in U.S. District Court in Cincinnati. He pleaded guilty in June to making bomb threats in Ohio and Kentucky.

The 43-year-old Purvis admitted creating an e-mail account under a fake name at a suburban Cincinnati hotel on Nov. 13, 2008, and e-mailing the FBI that he had planted bombs at Paul Brown Stadium, four Ohio River bridges, an Indiana casino and the Cincinnati/Northern Kentucky International Airport. He said the bombs would explode within a few days.

He was arrested a week later at an Erlanger, Kentucky, hotel. No bombs were found.
