Just days after it was painted, the Black Lives Matter mural outside Trump Tower was defaced.

Video taken Monday shows a masked man approaching the 5th Avenue art, and then taking a can of paint out of a bag, dumping it on the mural, and then fleeing the scene.

Red paint was splattered across the giant yellow letters.

Police say no arrests have been made yet.

Mayor Bill de Blasio tweeted that the mural has already been fixed.
