In December 2011, Qateel Siddiqui, a terror suspect, tells the Delhi and Bangalore Police that he was part of the German bakery terror plot. He says that Yasin Bhatkal was present with him till 2:30 pm at a hideout in Pune on February 13, the day of the bomb blast. There is no reference to Himayat Baig, the man who had already been charged for the blast by the ATS (see document 'IRs of Qateel Siddiqui' on the website).
The ATS now takes him under its custody and accepts all his revelations save one. They predate his presence with Yasin to February 11. Why? Because the ATS had already built a case showing Baig and Yasin being together on February 13 with no reference to any third person. A few months later, Qateel is killed in a high-security Pune jail.
