Questioned about the details in the chat, Yasin is believed to have told investigators he picked up the gelatine from a man identified only as Ibrahim from near the Swar Gate in Pune.
The ammonium nitrate used to make nine bombs for the May 2008 serial blasts in Jaipur, the chats indicated, was sourced from Udupi in Karnataka by IM operatives Atif Ameen and Ariz Khan.
Atif was killed in the Batla House encounter in September 2008 and Ariz is on the run.
