U.S. Secret Service officers arrested two people Monday morning near Lafayette Park, north of the White House, after a vehicle crashed onto a sidewalk and, around the same time, another person jumped a barricade, the agency said^2,6.

Secret Service Police and National Guard members responded just before 10 a.m. to the north side of the park at 16th Street and H Street Northwest, where a car had gone onto the sidewalk^2,4. The New York Times reported that the vehicle was a silver sedan and that it struck a historical sign north of the square¹. A Secret Service spokesperson said the driver was combative with officers and was quickly arrested^2,6.

The agency said a second person jumped a barricade near the northwest corner of Lafayette Park and was also quickly arrested^2,6. Reuters, citing the Secret Service, described the crash and the barricade jump as separate incidents and said it was not clear whether they were related⁶. Reuters also reported that President Donald Trump was at the White House and that the complex was briefly locked down⁶. The Secret Service moved reporters into the briefing room for a short time, according to accounts of the agency's response carried by Advance Local outlets².

Metropolitan Police explosive-ordinance technicians were called to sweep the vehicle as a precaution, and streets around the park were closed^2,5. The Secret Service said both matters remained under investigation⁶. Identities, charges and any connection between the two arrests were not released in the statements cited Monday^2,6.
