NEW DELHI: In a bid to appease Sikh supporters, chief minister Arvind Kejriwal has written a letter on Monday to Iqbal Singh, a Sikh leader who is presently camping at Jantar Mantar to demand justice for 1984 sikh riots.After representatives of Iqbal Singh met Kejriwal recently, he accepted at least two of their demands including release of Devinderpal Singh Bhullar who is allegedly guilty of killing nine persons in a car bombing intended to kill Congress leader Maninderjeet Singh Bitta.In the letter addressed to Iqbal Singh accessed by TOI, Kejriwal has assured Iqbal that the AAP government "is sympathetic to the issue and would take all necessary steps to ensure full justice. However the issues involved are very complex and require consultation at various stages. We will try to find solutions soonest," the letter says. It goes on to reveal that Kejriwal has already recommended the release of Bhullar.Another demand of the group is to set up a Special Investigation Team (SIT) to probe the 84 Sikh riots. To this Kejriwal has said that he does not have the powers set it up on his own but that he will write to the Lieutenant Governor suggesting that an SIT be formed.
