The Chinese authorities claim the reason behind the arrest being that Tsultrim was a 'separatist'.
Sources coming out of Tibet said that Tsultrim, who is monk from the Sog Tsanden Monastery located in Sog County, Kham Province in Eastern Tibet was taken a prisoner on the October 6, 2012.
At first, he was placed in Nagchu prison and there for a short period after which he was moved to a detention centre and for a period of four months and twenty-eight days, he was constantly moved between the two facilities.
After this, he was taken to Toelung prison in Lhasa where he was imprisoned for 3 months and eleven days, serving over 8 months in totality in prison.
He was finally released on May 11, 2013. During his imprisonment, Namgyal Tsultrim was heavily tortured and maltreated by the prison authorities. Now, out of prison, his body is nonresponsive and he has lost all use of his left arm.
Tsultrim was imprisoned on the allegations of being found with 4 CD's of His Holiness the Dalai Lama's teachings. The authorities called him a separatist belonging to Tibet. In 2011, some officials in Lhasa, after interrogating Tsultrim also said that he possessed contacts outside of Tibet.
Despite being released from prison, Tsultrim is subjected to continuous surveillance and interrogation by the Chinese authorities and there are still restrictions on him pertaining to various practices and his life continues to be a never-ending struggle.
