[1][5] There are many in-construction or proposed detention centres to be constructed following the exclusion of people from the final National Register of Citizens of India.
[8] The detention centers are commissioned as a place to house erstwhile residents who were excluded in NRC and finally declared illegal immigrants by the foreign tribunals of Assam.
[4][12] They were first intended as a location for "short-term detention of undocumented immigrants, refugees and people awaiting trial before a Foreigner’s Tribunals".
"[13] In 2011 the Assam government, when Congress was in power both at the Centre and in the state, had set up three detention camps[a] with hundreds of illegal immigrants.
