Capitol police officer dead, another wounded after car rams into barrier; suspect killed

The United States Capitol was locked down on Friday due to an "exterior security threat" after a car rammed into a barrier on the Senate side of the complex. One officer died and another was injured, according to United States Capitol Police (USCP), who said the suspect was killed by police after he exited his navy sedan and attacked them with a knife.

Fox News was told by security officials that the incident was believed to be a "lone wolf" attack.

The suspect, Noah Green, 25, was from Indiana and also had ties to Virginia.

Metropolitan Police Department Acting Chief Robert Contee said in a briefing the attack did not appear to be terrorism-related and the man had no known connection to a member of Congress. The suspect was not known to police.

The officer who died was identified as William "Billy" Evans. He had been a member of USCP for 18 years.
