"This individual threw a pastry he had hidden in his personal belongings at the Mona Lisa's glass case. This act had no effect on the painting, which was not damaged in any way."
He is currently under investigation for an "attempt to damage cultural property".
The man who was escorted out of the museum by security could be heard saying "Think of the Earth. That's why I did this. Think of the planet".
It might be among the more bizarre attacks on the painting but it is hardly the first.
Here are just some of the odd events inspired by the painting:
Mona Lisa: Portrait and projectiles
Paint, acid and the odd teacup have all been hurled at Leonardo Da Vinci's masterpiece over the years. Attacks became so regular that in 1950s, bullet proof glass was installed to protect the painting.
In 1956 two attacks, the first involving acid the second involving a rock, seriously damaged the painting.
In 1974, while on loan to Tokyo National Museum, she was the target of a vandal tagged the picture with red paint.
In 2009 a Russian woman threw a cup of hot tea at the painting.
Perhaps the most brazen, and successful, attack on the painting was in 1911, when thieves stole the picture. It was later discovered that two Italian employees of the Louvre had smuggled the picture out of the gallery, who attempted to sell it to the Uffizi in Florence.
Missing for almost three years, the picture was reprinted widely in newspapers of the day, leading to the painting finding international fame. Prior to this event, it was a little known exhibit among a catalogue of hundreds of thousands.
Today the Mona Lisa, 'jocund' 16 century Italian woman, is visited by around 9 million people a year.
