High-Speed Chase Ends In Gunfire A police officer has been injured after a woman reportedly led police on a car chase that ended in gunfire near the US Capitol in Washington. Witnesses said shots erupted after a woman driving a black Lexus was seen speeding up Constitution Avenue toward the Capitol Building with police in pursuit. The Associated Press reports the pursuit began when the car tried to ram a security barricade in front of the White House. Fox News, citing Capitol Hill sources, is reporting the female suspect was killed by police. Capitol Police have not confirmed her condition. Police seen moving through US Capitol.

Possibly we believe that there was a child in the car. Witnesses said at least 20 police cars chased the Lexus toward Capitol Hill, where the car crashed outside the Capitol. Police said one officer was injured in a car crash, but his injuries were not believed to be life-threatening. A lockdown was put in place at the Capitol and other federal buildings, but lifted about an hour after the shots rang out. First responders are seen aiding a victim at the scene Sky News US correspondent Amanda Walker, who is in Washington, said she heard a series of shots within minutes of each other before police swarmed the area. She said: "It was about 2.20pm local time and we heard a series of gunshots then and then there was a brief pause for around five minutes and then we heard further gunshots and that's when immediately we heard this cacophony of sirens, police cars and various units going around this area that is constantly so heavily-guarded." Senator Bob Casey told reporters he was walking from the Capitol to the Senate Russell Office Building across the street when he noticed several police officers driving fast up Constitution Avenue on motorcycles. He said: "Within seconds of that we heard three, four, five pops," which he assumed were gunshots. Television footage showed at least one person being removed from the scene on a stretcher. As a warning was sounded, the House abruptly went into recess and lawmakers left the chamber floor. The House had just finished approving legislation aimed at partly lifting the government shutdown by paying National Guard and Reserve members. People standing outside the Supreme Court across the street from Congress were hurried into the court building by authorities. The White House was quickly locked down after the incident at Capitol Hill and the stretch of Pennsylvania Avenue in front of the compound was closed to pedestrians. Secret Service said the procedures were precautionary. In a notice distributed by email, the US Capitol Police advised everyone to "close, lock and stay away from external doors and windows." The reports come two weeks after a deadly shooting at the nearby Navy Yard and amid a government shutdown.
