Two visitors to the Louvre in Paris were arrested Saturday after they installed two paintings in the Salle des États, which houses the Mona Lisa, according to a report by Agence France-Presse that cited police sources.

According to police, they stuck two paintings (each measuring about 11.8 by 15.7 inches) onto the walls of the Salle des États with sticky tape. One painting showed one of the suspects wearing a suit of armor, while the other showed the two with a woman. The Mona Lisa, which attracts crowds from opening to close, was not damaged in the incident.
