The chase ended when the vehicle slammed into a barrier and a police auto near the Library of Congress, according to reports.
The officer and driver of the vehicle suffered minor injuries.
The suspect, who hasn’t been publicly named by police, was charged with assault with a deadly weapon-vehicle, assaulting a police officer, aggravated reckless driving, and no valid permit.
Cops described “observing an erratic and aggressive” driver in the streets of Washington.
Police are searching the “suspicious” auto at Second Street SE and Pennsylvania Avenue SE.
“There is no evidence to indicate any nexus to terrorism at this time”, Malecki said in a statement.
Capitol Police warned there could be a loud noise as police “disrupt” the trunk of the vehicle.
The conditions of those who were injured were not known.
Barely an hour later, at about 1 a.m., the stabbing occurred in the 1500 block of Good Hope Road SE near Minnesota Avenue SE.
Police have said the incident is not terror related. They were seen in a black Toyota sport-utility vehicle on D Street. The officer in the cruiser sustained minor injuries.
