NEW YORK — A Manhattan art gallery featuring an exhibit observing the 100th anniversary of the Tulsa Race Massacre has been struck by vandalism.

Police released a video clip from a street security camera on Friday showing someone suspected of smearing white paint on the front window of the Black Wall Street Gallery earlier this week in SoHo. It was one of three acts of vandalism at the location in recent days that police were investigating as potential hate crimes.

Gallery owner Ricco Wright told police he discovered white paint on the windows on Monday and Tuesday, the 100th anniversary of the massacre on May 31 and June 1, 1921.

A post on the gallery's Instagram account also showed graffiti on the door that said, "ETC REAL ART."

The exhibit honors those killed in the 1921 Tulsa Race Massacre, in which a mob destroyed a Black community in Tulsa, Okla.
