China detains blogger for making political joke on Twitter BEIJING - Hundreds of Chinese Internet users are rallying around a Beijing blogger who's been detained by police after posting a joke on Twitter about the pivotal Communist Party congress. Zhai Xiaojun's Nov. 5 tweet suggested the next movie in the "Final Destination" horror franchise would be about the Great Hall of the People collapsing on party delegates. The tweet said, "An earthshaking debut will be seen at the global premiere on Nov. 8!" which is when the weeklong congress began. A Beijing police officer who would only give his surname, Sun, said Wednesday that Zhai was being investigated for "spreading terrorist information." Zhai's supporters call the allegation absurd. More than 400 people have signed an online petition urging authorities to release him.
