The Washington, DC Metropolitan Police Department told Sputnik that federal agents were investigating a suspicious package amid a bomb threat at the DoL building.
"We are assisting FPS [Federal Protective Services] in reference to a suspicious package and we're looking into it," the spokesperson said.
The two locations where road closures were mentioned by USCP - First St. and Constitution Ave. NW and First St. and Louisiana Ave. NW - are located due east of the DoL building, on the edge of the US Capitol grounds.
Just over a month ago, a man was arrested outside the Democratic National Committee headquarters south of the Capitol building with several large knives and neo-Nazi symbols etched on the side of his truck. A month earlier, another man was arrested near the US Capitol and the Library of Congress after threatening to detonate a bomb if US President Joe Biden didn't resign from office. The man surrendered to police without a fight.
Less than an hour after sending out the alert, USCP said the bomb threat "has concluded and all related road closures have reopened."
