Sangyip Prison Complex is a name used for a group of prison, detention and former labour-reform facilities in northeastern Lhasa, Tibet Autonomous Region, China. Human Rights Watch described Sangyip in the 1990s as a term used both for the wider complex and, more narrowly, for Yitridu, one of the facilities within it. Human Rights Watch listed the People's Armed Police (PAP) No. 1 Branch as a probable official designation associated with the complex.[1]
Sangyip has a long history of holding Tibetan political detainees. Takna Jigme Sangpo was reportedly imprisoned at Sangyip in 1964, demonstrating that a detention facility using the name existed by that date.[2] Human-rights organisations have documented allegations of torture, ill-treatment and compulsory labour involving prisoners held at facilities described as part of the Sangyip system.[1][3]
Notable detainees have included Takna Jigme Sangpo,[2] Yeshi Gyatso,[4] and Palden Gyatso.[5]
History
[edit]Sangyip is documented as a place of detention by at least the 1960s. Takna Jigme Sangpo was sentenced to three years' imprisonment there in 1964 and was again imprisoned at Sangyip following a further sentence in 1970.[2]
In a 1978 survey of political imprisonment in China, Amnesty International reported allegations that Sangyip held approximately 1,800 prisoners in 1972, most of whom were described by its sources as Tibetan political prisoners. The report stated that prisoners performed work including stone-quarrying, brick-making, blacksmithing, building construction and carpentry.[3]
By the late 1980s and early 1990s, several separate detention and labour-reform institutions in northeastern Lhasa were being referred to collectively as Sangyip. Human Rights Watch's 1996 survey distinguished Yitridu, Seitru and Outridu as separate facilities within the Sangyip complex.[1] The report described Sangyip as an ambiguous name which could refer either to the entire complex or specifically to Yitridu.[1]
Outridu, also known as Wuzhidui or Number Five Unit, had previously operated as a laogai and subsequently as a laojiao facility. Human Rights Watch reported that many political prisoners detained there after the 1989 unrest in Lhasa were transferred to the newly established Trisam facility in 1992. The transfer may have followed a protest by prisoners at Sangyip on 20 May 1991.[1]
The International Campaign for Tibet (ICT) later identified Outridu/Utritu with Lhasa Prison. ICT reported that Utritu was completed by 1988 and subsequently became increasingly known as Lhasa Prison. It remained part of the group of facilities collectively referred to as Sangyip.[6] Lhasa Prison continues to operate as an institution of the Tibet Autonomous Region prison system.[7]
Facilities
[edit]The precise composition of the Sangyip complex has varied between sources and over time. Human Rights Watch identified several distinct institutions associated with the name in the 1990s.[1] A 2021 open-source investigation by the Tibet Research Project attempted to resolve the naming and location ambiguities through analysis of historical satellite imagery, photographs, mapping services and open-source documents.[8]
| Facility / unit | Alternative names | Coordinates | Notes |
|---|---|---|---|
| Yitridu | Yizhidui; Section/Unit No. 1; sometimes itself called Sangyip | 29°41′38″N 91°10′03″E / 29.69382388°N 91.16736717°E | Human Rights Watch described Yitridu as either a laojiao or a semi-custodial "forced job placement" facility associated with the Sangyip complex.[1] The Tibet Research Project proposed a possible location northeast of the other facilities, but explicitly described this identification as unconfirmed and speculative.[8] |
| Seitru / Sitru | Si chu; Number Four Branch/Unit; Tibet Autonomous Region Public Security Bureau Detention Center | 29°41′28″N 91°09′28″E / 29.69115449°N 91.15785966°E | Human Rights Watch identified Seitru as the Tibet Autonomous Region-level detention centre within the Sangyip complex, historically used for detainees who had not yet been formally charged and for some state-security cases.[1] ICT identifies it as the Tibet Autonomous Region Public Security Bureau Detention Center immediately north of Utritu.[6] The Tibet Research Project geolocated the facility and, using historical satellite imagery, found that the older complex was demolished between 2013 and 2014, rebuilt during 2014–2015 and substantially expanded by 2018.[8] |
| Utritu / Utritru | Outridu; Authitu; Wuzhidui; Number Five Unit; Lhasa Prison | 29°41′06″N 91°09′33″E / 29.6850411°N 91.15916768°E | Formerly a labour-reform and re-education-through-labour facility. Most known political prisoners were transferred to Trisam in 1992.[1] ICT identified Utritu as Lhasa Prison and described it as part of the Sangyip group.[6] The Tibet Research Project independently geolocated the facility and used satellite and ground-level imagery to verify its layout.[8] The modern Lhasa Prison remains operational.[7] |
| Unidentified facility 2968591154 | — | 29°41′07″N 91°09′16″E / 29.68525453°N 91.15448533°E | A secure facility immediately west of Utritru identified by the Tibet Research Project as a prison or detention centre. The project considered it possibly part of Utritru or the wider Sangyip complex but did not establish its official name.[8] |
The Tibet Research Project noted that the similarity of names such as Yitridu, Utritru, Outridu and Sangyip had resulted in repeated conflation of separate facilities in published material. Its investigation treated Sitru and Utritru as geolocated facilities with strong supporting evidence, while treating the proposed Yitridu location and the relationship of the unidentified facility to the wider complex more cautiously.[8]
Human rights reporting
[edit]Human Rights Watch documented the detention of numerous Tibetan political prisoners at Sangyip-related facilities during the late 1980s and 1990s. Its 1996 report stated that Seitru was used particularly for investigations involving suspected political and state-security offences, while Outridu had held many people detained following unrest in Lhasa in 1989.[1]
Former prisoner Palden Gyatso testified that he was detained at "Old Sangyip Prison" following his arrest in 1983 and was later transferred to Outridu. In testimony entered into the United States Congressional Record in 1995, he described compulsory labour, beatings and torture during his imprisonment.[5]
ICT has similarly reported allegations of severe torture and ill-treatment at detention facilities in Lhasa, including Sitru, and has documented the expansion and modernisation of several prison and detention compounds in the city.[6]
