Four Tibetans, Tamding Gyal, Dhundup, Chakdha Gyal, and Yarkho, have been arrested in Rebgong during a routine search for having pictures of the Dalai Lama in their cell phones. Following the series of self-immolations in the area, Chinese authorities have been inspecting electronic devices of local Tibetans to see if they have tried to make any contacts outside the region. Local authorities have regularly used tactics such as communication blackouts and inspections of electronic devices in an attempt to contain the spread of information.
