Thubten Kelsang Thalutsogentsang, a 43-year-old former Tibetan monk and horse-cart driver, was first detained following the 1959 Tibetan uprising and reportedly imprisoned in Sangyib Prison, Lhasa, where he was assigned to a labour unit and remained under official surveillance after his release. On 3 December 1981, he was re-arrested in Lhasa for allegedly shouting pro-independence slogans in support of Tibetan independence during a public gathering. He was reportedly sentenced to three years' imprisonment. No reliable information is available regarding his treatment, release, or current whereabouts following his arrest.
