China’s best-known artist, Ai Weiwei, remains missing more than a day after he was detained by Chinese police. Chinese authorities detained him and his wife on Sunday and seized more than 30 computers from his studio. Weiwei is best known for designing the Bird’s Nest stadium for the 2008 Olympic Games in Beijing. In March, Weiwei accused the Chinese government of trying to silence dissident voices.

Ai Weiwei: “Any tiny piece of information can be a fatal blow to them. For example, someone says something about jasmine. No one even knows who the person is, they haven’t shown their face, but they can draw the support from a lot of young people.”
