The rioters of the 1984 Sikh carnage, in which over 3000 people were killed in Delhi, were apparently paid Rs 500 for each person they killed, a new book on the riots reveals, reinforcing the allegation that the violence far from being spontaneous was the outcome of a conspiracy. The book, titled When A Tree Shook Delhi, written by journalist Manoj Mitta and advocate for many of the riot victims' families, H S Phoolka, claims to give an "uncensored" insight into the events. The book traces the genesis of the violence through eyewitness accounts and the investigations by Phoolka as counsel for victims.
