The niece of a prominent Tibetan religious leader has fled China and arrived in exile in northern India to reveal what his family says is the truth about his death.

Nyima Lhamo told the Associated Press late Wednesday that his family believes Tenzin Tulku Delek's death in a Chinese prison last year was not from a heart attack as Chinese officials said, but the result of torture.

Nyima says her uncle told her mother during prison visits that he was beaten and starved. After his death his family was allowed only a few minutes with the body but other monks told them that his nails were black and he had a deep hollow behind his head.

Nyima arrived in the northern hill town of Dharmsala via Nepal on Sunday.
