The family was informed Sunday that Tenzin Delek Rinpoche, 65, died 13 years into a life sentence on charges of financing and supporting a series of terrorist bombings and secession activities. His supporters say the charges were false.
The prison has not produced the lama's body after two days of negotiations between the police and the monk's immediate family, the New York-based Students for a Free Tibet said Wednesday in a statement. The family wants to perform Tibetan Buddhist funeral rites on the body.
Calls to the prison were unanswered Wednesday. Tenzin Delek was arrested in 2002 in connection with a blast in Chengdu city that wounded three people.
Human rights groups have long said the lama was persecuted by the Chinese and arrested on false charges because he advocated for Tibetan rights. His death sentence was later commuted to life in prison. He continued to maintain his innocence.
Last year, the monk's family had applied for medical parole for him on the grounds that he suffered from a heart condition, high blood pressure, dizzy spells and problems with his legs that had caused him to fall down frequently.
Authorities never responded to the request.
