from washington post: Thousands of people thronged a police station in southwestern China to protest the alleged coverup of a teenage girl's rape and murder, witnesses and officials reported Sunday. The crowd set fire to a government building complex and several police vehicles. The violence, which began Saturday, was brought under control by authorities around 2 a.m. Sunday. There were conflicting reports about the number of injuries and arrests as news of the riot spread over the Internet. Pictures and video from the incident were posted on Chinese online discussion forums and Web sites but quickly became inaccessible, ostensibly as government censors stepped in.
