The first reported demonstration during the 2008 Tibetan uprising anniversary was on 10 March 2008, when a group of 300-400 monks from Drepung monastery marched to Lhasa's center demanding religious freedom and the release of Drepung monks arrested a year earlier. Chinese police blocked their route, and a sitting protest began. Reportedly, some monks were thrown to the ground and kicked, and up to 60 monks were arrested.
