Followers and students of Tulku Tenzin Delek Rinpoche have launched a DVD and appealed for the immediate release of the highly revered Lama who is currently serving life sentence in a Chinese prison. Relatives say that his health has continued to deteriorate over the last 11 years. Reports in 2011 revealed that Rinpoche was suffering from a heart ailment. He was sentenced in 2002 in a bomb blasts case.
