Story highlights Suspect Larry Russell Dawson, 66, is in stable but critical condition

He faces charges of assault with a deadly weapon and assault on a police officer while armed

No U.S. Capitol Police officers were injured

Washington (CNN) U.S. Capitol Police shot a Tennessee man Monday afternoon after he pulled out what appeared to be a weapon at the Capitol Visitor Center, law enforcement officials said.

A female civilian bystander was injured by shrapnel, but no U.S. Capitol Police officers were injured.

"We believe this is an act of a single person who has frequented the Capitol grounds before, and there is no reason to believe this is anything more than a criminal act," U.S. Capitol Police Chief Matthew Verderosa said.

Police said the suspect, Larry Russell Dawson, faces charges of assault with a deadly weapon and assault on a police officer while armed. He underwent surgery and was in stable but critical condition Monday.

Once released from the hospital, the 66-year-old will be presented to the District of Columbia Superior Court, U.S. Capitol Police said.
