Source coming out of Tibet says a Tibetan man was detained by Chinese police in Karze County of eastern Tibet after staging a lone protest calling for "long life of His Holiness the Dalai Lama".

"Sangye, a 29-year-old Tibetan was arrested by Chinese authorities following a solo protest against China's suppression of religious freedom and Tibetan culture, on November 27, 2015," a former political prisoner currently living in Belgium with close contacts in the Tibetan region told the Tibet Post International.

"Sangye staged the protest at the main market square of Karze county in traditional province of Tibet (Ch: Sichuan Province), on Friday morning." he said, adding that "the current condition and whereabouts of Sangye remain unknown."
