Rinchen, a Tibetan living in Belgium said that "Chinese authorities in Sog County (Ch: Suo, Naqu, Prefecture, Tibet Autonomous Region) Kham region of eastern Tibet arrested five Tibetans, including two monks for their role in allegedly sending out photographs and information spreading information dealing with the political situation in Tibet."
"The two monks of Drilda monastery in Sog County of eastern Tibet have been identified as Kalsang Tsultrim and Thupten Palden," Rinchen told The Tibet Post International, adding that "the current condition and whereabouts of the arrested monks remain unknown."
"The three lay men detained were identified as Norbu Dhondup, Monlam Gyatso, and Tsering Tharpa, all the three were from Dhowa village in Sog County, Eastern Tibet," Rinchen added.
"Their whereabouts and condition remain unknown. Moreover, local Chinese authorities have not given any reason to their family for their arrest," he said.
Sources said that they were detained on March 6, 2014 for allegedly sending photographs and messages considered subversive by the Chinese government through mobile phones.
On March 10, over 20 Chinese military convoys with more than 80 security forces have arrived in the areas, as the authorities have imposed a heavy restriction after the incident.
Sources also stated that eyewitness saw a huge bridge in Drido Township displayed "Tibet Is An Independent Nation" written in large Tibetan letters with red color.
Arbitrary arrests and detention have increased amid unusual intensification of state surveillance measures in the region. The military and police presence is reported to have significantly increased recent days.
Chinese authorities are isolating Tibet from the world, particularly in the areas where the self-immolation protests are happening. Tibetans face lengthy jail sentences and torture for sharing information about any protests, including the self-immolations.
