A man briefly disrupted the Jeff Koons retrospective at the Whitney Museum this afternoon, splashing red paint against a wall and signing his name. He did not vandalize any artworks.

According to artist Laura Higgins Palmer, who alerted Hyperallergic to the intervention, the man threw red paint against the wall in a gallery on the third floor. Palmer said she was taking a selfie of her reflection in one of Koons’s silver bunnies when she noticed a man walking by with a black bag. When she turned around, he was splashing paint on the wall, in what appears to be a kind of double X shape, although it could also be a human figure with arms and legs spread.
