Several streets were closed for nearly four hours and a coffee house was evacuated on Monday after a vehicle struck a barrier and a police car near the U.S. Capitol, according to authorities.

Police used explosives to open the vehicle’s trunk and, after a long investigation that disrupted traffic, determined that there was nothing suspicious inside.

“The vehicle was cleared with negative results,” Capitol police said in a statement, adding, “There is no evidence to indicate any nexus to terrorism at this time.”

A spokeswoman for the Capitol Police said the vehicle’s driver was taken to a hospital for treatment of minor injuries. The spokeswoman said he has been charged with assault with a deadly weapon, felony assault on a police officer, aggravated reckless driving and driving without a permit.

His name was not immediately released.

The incident occurred about 11:45 a.m. at Independence Avenue and Second Street SE. Authorities said a Capitol Police officer was slightly injured in the crash and also was taken to a hospital for treatment. He has been released.

Police evacuated people in a nearby coffee shop and blocked off several streets. All roads except Independence Avenue between Second and Third streets reopened shortly before 3:30 p.m.
