Ogyen, a 20-year old Tibetan student, was shot and killed after police opened fire into a crowd of Tibetans gathered in protest on January 26, 2012 in Dzamthang county, Ngaba Tibetan Autonomous Prefecture, Sichuan. The protest was in opposition to the detention of another young Tibetan, named Tarpa, who was taken into custody after posting leaflets stating that the self-immolation protests in Tibet were calls for Tibetan freedom and for the return of the Dalai Lama, and that the self-immolations would continue until authorities met these demands.
