The U.S. Capitol was locked down and a police officer reportedly injured Thursday when a woman driving a black Infiniti led police on a chase from the White House to Capitol Hill.
The woman was shot by police and later died of her injuries. A child in the woman's car appeared uninjured.
“There is no indiction this is related to terrorism or that it's anything other than an isolated incident,” Capitol Police Chief Kim Dine said.
Police said the unidentified woman, whose car had Connecticut license plates, rammed a barricade along Pennsylvania Avenue near the White House before leading police in a high-speed chase down Pennsylvania Avenue, running red lights as she raced toward Capitol Hill.
The woman's car came to a stop at Second Street and Maryland Avenue just outside the Capitol and gunfire erupted.
The Capitol was locked down by police around 2 p.m. Lawmakers and their staffs were told to take shelter in their offices, away from doors and windows. The lockdown was lifted about an hour later.
The White House on Thursday said President Obama had been briefed after reports of gunfire at the Capitol.
"White House staff are in touch with law enforcement and monitoring the incident," said a White House official. "Questions about the security posture at the White House complex should be directed to the United States Secret Service."
