The SIT filed a chargesheet on Wednesday against social activist Teesta Setalvad, former DGP RB Sreekumar and ex-IPS Sanjiv Bhatt, citing 90 witnesses in support of charges of fabricating evidence to frame 63 persons for a purported “larger conspiracy behind the 2002 riots”. Sreekumar and Bhatt are behind bars, while Setalvad has been granted interim bail by the SC in this case.
