Anton Caluori, 31, appeared in Federal Court on Wednesday. He was taken into custody at his apartment Tuesday by the US Secret Service and Federal Way Police.

The U.S. attorney's Office reported Caluori threatened to kill President Obama in an e-mail sent to a general purpose FBI address.

The Secret Service says Coluori wrote the following to the FBI on Tuesday:

"I will kill the president. I don't give a f*** but you know that."

He also gave his address in the vulgar e-mail, challenging them to "get here now."

The message was intercepted and police tracked his location to make an arrest.

Documents say when Caluori opened the door of the apartment he shares with his mother, he was wearing a bandoleer filled with 12-gauge shotgun shells around his torso, and attached to the bandoleer was a large knife. He was wearing a revolver in an ankle holster.

His right hand was out of view, and when the Secret Service agent and Federal Way Police officer repeatedly told Caluori to show them his hands, he moved his right hand from behind his back, revealing a "stockless, pump-action shotgun with pistol grip."

Caluori raised the shotgun, pointing it at the agent and officer, who were able to wrestle him to the ground.

When he was asked if there was anything in the house that would hurt officers, Caluori replied “There are things inside that go boom.”

The apartment complex was swept by the bomb squad, but nothing was found.

Documents say inside the apartment police found a laptop computer that was powered on and displaying the e-mail address the threatening e-mail came from.
