 In 1984, a fact-finding team jointly organized by People's Union for Democratic Rights (PUDR) and the People's Union for Civil Liberties (PUCL) concluded that attacks on members of the Sikh community in the 1984 anti-Sikh riots were not from spontaneous outrage over the assassination of Indian prime minister Indira Gandhi, but rather the result of deliberate planning by important politicians of the Indian National Congress party.The investigators found that the member of parliament who was most commonly named by Sikh riot survivors for being responsible for the attacks in Delhi locality of Sultanpuri was Sajjan Kumar.Similarly, Sikh riot survivors in the locality of Mangolpuri nearly unanimously named Kumar as having "masterminded the violence".
