A large porcelain sculpture by the Chinese dissident artist Ai Weiwei was left shattered Friday after a man smashed the artwork on display at a museum in Bologna, Italy.

Ai shared security footage of the act of vandalism on his piece, titled Porcelain Cube, and video of the suspects arrest outside the Palazzo Fava museum on his Instagram with a message to people who destroy art.

You are literally ruining the things that make this world beautiful and cultured. Instead of destroying things in museums, how about you go destroy things actually hurting our planet and societies? wrote Ai, a vocal critic of the Chinese government whos been essentially exiled from his country.
