A federal grand jury has indicted a man who walked into the Wells Fargo building in downtown Salt Lake City, carrying what he claimed was a backpack full of explosives.

Nicholas Glenn Dotson, 48, was indicted today on charges of threatening the use of explosives and a hoax. The indictment said Dotson walked into the Wells Fargo building on July 17, claiming his backpack had five pounds of explosives that he would detonate.

The skyscraper was evacuated. The bomb scare turned out to be a hoax. Dotson is being held in the Salt Lake County Jail.
