The Rajasthan Police say they cannot conclude that the bombs were made in Delhi or its neighbourhood, but suspect that there’s a trail to pick up along Delhi-Ghaziabad-Bijnore. And it’s hoping new clues will emerge after scanning the mobile calls made 30 minutes before and after the blasts.

Two rounds of interrogation of SIMI general secretary Safdar Nagori has yielded litle information on which terror group was behind the blasts. After interrogating him, the Rajasthan Police picked up Mohammed Ilyaas, a cleric in a Bharatpur mosque. Ilyaas, according to the Rajasthan Police, was an accomplice of Yaqub Khan, a key suspect in the 1993 Mumbai serial blasts. The interrogation of software engineer Rashid Hussain, picked up on the basis of Nagori’s questioning, has yielded nothing.
