Takna Jigme Sangpo, who served over 30 years in prison in Chinese controlled Tibet, has died in Switzerland at the age of 91. Tagna was a school teacher in Lhasa in 1960 when he was first arrested for “corrupting the minds of children with reactionary ideas.” He was later convicted for propaganda offences and sent to a work camp in 1979. In 2002 he was released into exile in Switzerland.
