Following the government’s regulations that demonstrations would be allowed in designated parks during the Beijing Olympics, Mr. Li Jincheng and Mr. Liu Xueli applied for and obtained permission to protest in World Park. They were told to come to the authorities to get their written permission on August 9.
But on August 8, Mr. Li mysteriously disappeared near the “Bird’s Nest” Olympic Stadium. The other organizer, Mr. Liu, was also missing. Their protest permit has been invalidated.
