Assam NRC authorities have ordered district officials to delete the names of "ineligible" persons from the "final" list that was published in August last year. The names to be deleted run into the thousands, a top NRC official said. A letter from Hitesh Dev Sarma, the state's senior-most NRC official, to deputy commissioners (DC) and district registrars of citizen registration (DRCR) in each of Assam's 33 districts also asks them to issue speaker orders for detention to these thousands of people, sources within the NRC said.
