"Tsultrim Nyendak, 40, a senior teacher from Rabten Monastery in Tsachu Township in Driru County (Chinese: Biru County in Naqu Prefecture, Tibet Autonomous Region (TAR), was sentenced to 9 years' in prison by an Intermediate People's Court in Lhasa," Samdup, a Tibetan from Belgium told The Tibet Post International (TPI) on Tuesday.
"Locals claimed he was too weak and the Chinese authorities have denied requests from family members and relatives, urging for the release of Nyendak in order to get medical treatment."
'Despite his critical health condition, Nyendak is currently serving his sentence in Chushul Prison on the outskirt of Lhasa city,' Samdup said, citing sources in the region dated July 31.
TPI had previously reported the Chinese police arrest of Nyendak, a senior monk from Rabten Monastery in Tsachu Township.
However, the source said that 'details about trial date and charges are still unknown, making it difficult to conclude whether Nyendak was held illegally for nearly a year before his sentencing.'
'It is also unknown whether or not the Chinese authorities informed his family members about the prison sentence that had supposedly taken place prior to the sentencing,' according to the sources.
It was previously reported that hundreds of Tibetans, including Buddhist monks have been targeted, arrested or disappeared since crackdown began in 2013 in Driru County in the name of Chinese president Xi Jinping's "mass line" campaign last year. Many are targeted and arrested on false pretext and the fate of many more remain unknown due to restrictions on communication lines.
