“The incident took place on December 28, when Shakeel Massey, a Spanish architecture student, punched Picasso’s 1944 painting Bust of a Woman numerous times. He held metal padlocks and wrapped his hand in a scarf to break through the protective glass, ripping the canvas before tearing it off the wall. Museum visitors looked on in shock as security guards detained him. Massey told the guards at the time that the act was a ‘performance.'” – Artnet
