Days after the violent crackdown on local Tibetans in Diru County in Nagchu (Ch: Naqu) Prefecture, Chinese authorities in Lhasa City have issued a notification to various ‘convenience police posts’ in Lhasa and Nagchu to monitor the movement and activities of Nagchu Tibetans.
Human Rights Watch had earlier reported that by July 2012, 676 permanent “convenience police-posts” (Ch.: bian minjing wu zhan) had been set up in Tibet Autonomous Region (TAR). These are manned by police officers who are on duty around-the-clock.
According to the notification, police officers would use secret codes when relaying information in real time about the movement and activities of Tibetans visiting Lhasa from Nagchu. The notification mentions that police officers would use secret codes for Diru (Ch: Biru) County, Drachen (Ch: Bachen) County and Sog (Ch: Suo) County, all located in the eastern part of Nagchu Prefecture, when relaying information about individuals from these areas. For instance, the secret code for Diru County is “A”. It appears that each county in Nagchu Prefecture has been assigned a secret code for police surveillance.
