Washington FOX News The United States Capitol was locked down on Friday due to an “exterior security threat,” as the United States Capitol Police (USCP) said one officer died and another was injured after a car rammed into them. Sources said the suspect exited his car wielding a knife and was shot by the USCP, dying of his injuries.

Police identified the slain officer as William “Billy” Evans, an 18-year veteran who was a member of the department’s first responders unit. Authorities said the attack did not appear to be related to terrorism.

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

The crash and shooting happened at a security checkpoint near the Capitol as Congress is on recess. It comes as the Washington region remains on edge nearly three months after a mob of armed insurrectionists stormed the Capitol.
