A 36-year-old man who masqueraded as an old woman has been arrested after he smeared cake across the glass protecting the Mona Lisa at the Louvre in Paris.

As the Associated Press reported, the French capital’s prosecutor’s officer confirmed the man’s arrest following the incident on Sunday, and he has since been taken to a police psychiatric unit. Videos shared on social media appeared to show the man, who was in disguise in a wheelchair, being escorted from the scene as someone cleaned the cake off the glass. The actual moment the man threw the cake, after supposedly throwing roses at museum patrons, does not seem to have been captured on video.
