Tibetan writer Zhogs Dung was arrested by Chinese police on Friday report Tibetan  sources. Although officials have declined to comment on his detainment, it is assumed that his arrest was related to open letter he signed with other Tibetan intellectuals criticising the government’s relief effort after the Qinghai earthquake. The letter first published on the Tibetan website www.sangdhor.com (temporarily defunct) states that “news from the mouthpiece for the party organisations can not be believed” and also reminds people to not send donations directly to government organisations due to corruption. The Oslo-based Voice of Tibet radio station reports that its transmissions in China have been jammed for two days, despite the fact that the majority of its broadcasts have been messages of condolence from exiled Tibetans.
