(The Hill) — U.S. Park Police arrested a man on Tuesday evening who they said vandalized the base of the Washington Monument.

“The United States Park Police has an adult male in custody for vandalizing the base of the Washington Monument with paint,” the agency said in a statement. 

“The area at the base of the monument will be temporarily closed,” the statement said. “National Park Service conservators will work on the restoration process. The investigation is ongoing and there is no more specific information at this time.”

Photos of the alleged incident posted on Twitter show red paint smeared on the west side of the monument’s base.

“Have you been f—— by this,” the vandal wrote in paint with an arrow pointing upward toward the monument.

The monument, which stands at 550 feet tall, is shaped like an obelisk, with four tapering sides leading to a pyramid shape at the top. It is located on the National Mall in between the Lincoln Memorial and the Capitol Building.

“Gov says tough s——,” the alleged suspect appeared to write on the monument.
