The truck driver who plowed through security barriers close to the US White House has been taken into custody.
He faces charges for a number of crimes, including dangerous driving.
There were no injuries, according to a Secret Service official, and preliminary inquiries pointed to the possibility that the collision was deliberate.
The driver, a 19-year-old Missouri guy, is accused of hurling threatening remarks at Vice-President Kamala Harris and President Joe Biden.
US Park Police named the suspect as Sai Varshith Kandula, from St Louis suburb of Chesterfield.
He is accused of trespassing, damaging government property, operating a vehicle recklessly, threatening to kill the President, Vice-President, or a member of their family, and assault with a dangerous weapon.
According to Police, neither bombs nor firearms were discovered inside the car.
US media sources say a roll of duct tape, a black rucksack, and a Nazi flag were discovered inside the truck.
The incident, which occurred just before 2:00am, local time, caused the historic Hay-Adams hotel to be evacuated.
Following a series of incidents in recent years, security has been stepped up at the White House and other federal facilities in Washington DC.
