see below link. Its a report that was written by a New Delhi based Human Rights Organisation about 20 days after the Anti-Sikh Riots in Delhi.
"A fact-finding team jointly organised by one People's Union for Democratic Rights (PUDR) and people's Union for Civil Liberties (PUCL) in the course of investigations from November 1 to November 10, has come to the conclusion that the attacks on members of the Sikh Community in Delhi and its suburbs during the period, far from being a spontaneous expression of "madness" and of popular "grief and anger" at Mrs. Gandhi's assasination as made out to be by the authorities, were the outcome of a well organised plan marked by acts of both deliberate commissions and omissions by important politicians of the Congress (I) at the top and by authorities in the administration. Although there was the handiwork of a determined group which was inspired by different sentiments altogether."
"Experience of individual members of the team as well as their extensive interviews with the (I) victims of the riots (ii) police officers who were expeted to suppress the riots, (iii) neighbours of the victims who tried to protect them, (iv) army personnel and v) political leaders, suggest that the attacks on the Sikhs followed a common pattern, whether they took place in Munirka in the South, or Mangolpuri in the West, or Trilokpuri in the east. The uniformity in the sequences of events at every spot in such far-flung places proves beyond doubt that the attack were master minded by some powerful organised groups. As a senior army officer deployed in Delhi during the recent riots said : "This arson is the work of an expert". Newspaper reports suggest that this pattern is similar in all Congress (I) ruled states."
