(CBS) - A law enforcement source says a young child was found in the car of a woman who tried to WUSA reports.
U.S. Capitol Police Chief Kim Dine told reporters the woman was in "very, very bad shape."
"We have no information that this was related to terrorism or that this was anything other than an isolated incident," said Dine.
Dine said one police officer was "struck in his squad car" and "appears to be conscious and breathing."
WUSA reports a male was also found in the vehicle the woman was driving.
CBS News reports that the woman tried to crash into a gate near 15th Street and Pennsylvania Avenue, NW, which is near the White House and Treasury Department. She then drove away and was pursued by Secret Service and other law enforcement.
