A man in a wig was detained after throwing a piece of cake at the Mona Lisa

A man who seems to have been disguised as an old woman in a wheelchair threw a piece of cake at the Mona Lisa in Paris.

Social media shows security guards at the Louvre Museum escorting the man away Sunday as he spoke in French about the planet

Consider the Earth! There are others that wish to destroy the planet! Consider it.

Think of the Earth, say the artists. According to The Associated Press, "that's why I did this."

Another video showed someone clearing the cake off the glass protecting the Mona Lisa

Onlookers used their phones to record the aftermath of the incident.

The 36-year-old man was detained and sent to a psychiatric unit, according to the AP.

The original Mona Lisa was painted by Leonardo da Vinci between 1503 and 1519.

The oil painting hangs in the Louvre's largest room, according to the museum's website.

This isn't the first time the iconic painting has run into trouble.

The protective glass was put up after it was damaged in an acid attack during the 1950s.
