The man who rammed a auto into two officers at a barricade outside the U.S. Capitol, killing one of them before he was shot to death by police, had been suffering from delusions, paranoia and suicidal thoughts, a U.S. official told The Associated Press on Saturday.
Capitol Police say a suspect "rammed a vehicle" into officers at a vehicle access point to the Capitol complex in Washington, before getting out of the vehicle, holding a knife, and attacking officers there. Green died at a Washington, D.C. hospital.
In a tweet, the police department said the condition of the second officer was stable and non-threatening. They identified the suspect as Noah Green, 25.
Police said Green rammed his auto into the officers at 1:02 p.m. and then exited the vehicle and lunged at them.
The suspect was shot and killed by one of the officers after exiting "the vehicle with a knife in hand" and "lunging" at the officers, Yogananda Pittman, the acting Capitol Police chief, said at a press conference.
In one post he spoke of being tormented by the Federal Bureau of Investigation and Central Intelligence Agency, hospitalised and subjected to "mind control", and called the government "the #1 enemy of Black people!"
Shortly after 1 p.m., Capitol Police sent an initial alert to congressional staffers, warning them of an "external security threat".
President Joe Biden, who was with first lady Jill Biden at Camp David for the Easter holiday, offered his "heartfelt condolences" to the family of William Evans, the veteran policeman killed in the attack.
House Speaker Nancy Pelosi ordered flags lowered to half-staff on the Capitol, calling Evans "a martyr for our democracy". The Capitol Police last week began taking down some of the security fencing around the outer perimeter of the complex, easing up on checkpoints and allowing cars to drive closer to the halls of Congress.
"At a time of such suffering, no words are adequate".
"Officer Evans, his family, and all those who knew him are in our hearts and prayers".
Capitol Police said that the Evans family is asking for privacy at this time.
Five people died in the January 6 riot, including Capitol Police officer Brian Sicknick, who was among a badly outnumbered force trying to fight off insurrectionists who supported former President Donald Trump's bid to overturn the election.
