Man smears cake on Mona Lisa in an apparent environment-related publicity stunt.
The Mona Lisa painting placed at Louvre Museum in Paris was smeared with cake by a man disguised as an old woman.
The man entered the museum as an old lady on a wheelchair.
Before smashing the cake, he tried to break the protective-glass on the painting.
The artwork remained unharmed as the man could not break the glass and smear cake directly on the painting.
The man looked like a climate activist pulling off an environment related publicity stunt.
Later, the painting was cleaned and the man was detained.
