Those who witnessed the moment told on social networks that the police authorities acted promptly, expelling the attacker. \u201cVery heavy to have witnessed this,\u201d said Twitter user Lis Grimaldi (@Lis_grimaldi), who posted a video on her profile at the scene shortly after the attack. According to user @Aluferathul, there are even more surprises about the act: \u201cIt was a man, who was in a wheelchair with wig, who got up from his chair very determined and threw the pie,\u201d he said. The information has not yet been confirmed by the museum. The work was not damaged, as the pie collided with the glass that protects the painting.
