A 48-year-old man admitted Tuesday morning in federal court to walking into a downtown bank last July and telling the bank's manager that he had a backpack full of explosives.

During a plea hearing in U.S. District Court, Nicholas Glenn Dotson said he entered the Wells Fargo building on 299 S. Main on July 17 and asked to speak with the bank manager.

Dotson said he told the manager that he was interested in opening an account and was led into the manager's office where he told the manager he had five pounds of explosives in his backpack and to call 911. He then ordered the manager to clear the building.

While on the phone with a police dispatcher, Dotson said he told police he had explosives several times during the course of seven phone calls. At one point, Dotson said he felt police were "jerking him around" and reminded the dispatcher he had a "(expletive) explosive device."

Eventually Dotson surrendered to police and a bomb squad detonated his backpack, only to find out his threats were a hoax. The threat led to the evacuation of the building as well as interruption of TRAX service downtown.

Dotson was indicted by a federal grand jury last October on two counts of making threatening communications about an explosive device and one count of using a hoax device.

In court Tuesday, Dotson pleaded guilty to one count of making threatening communication, which carries a maximum penalty of 10 years.

Federal prosecutors have agreed to move to have the two other counts dismissed and to recommend a lower sentence for his acceptance of responsibility.

Sentencing has been set for March 25.
