Police detained Khenpo Jinpa in August 2006 on suspicion of distributing leaflets calling for Tibet's independence and the Dalai Lama's long life at a festival the previous year, the centre said in a statement faxed to Reuters.
The Dalai Lama, Tibet's spiritual leader, has lived in exile in India since 1959 when he fled his predominantly Buddhist homeland after an abortive uprising against Communist rule.

In 2001, hundreds of monks' huts at the institute were destroyed by paramilitary police and a ceiling of 1,000 monks was imposed against the total enrolment of about 10,000.
