According to the narco test, it was decided that they would strike in various parts of the country using the bombs, which only needed a timer device to be attached before use.

Intelligence Bureau officials told rediff.com that the police tracked down the SIMI activists in Indore based on information obtained from Ghouse's narco analysis.

Ghouse revealed at least 15 SIMI operatives are still at large and that each of them has an assembled bomb with him. He added that they are to meet once again to decide on the target and time of attack. Likely targets include Karnataka, Goa [Images] and Madhya Pradesh, he said.

IB sources say a massive manhunt has been launched to track down these missing men. The agency is gathering telephone intercepts and other information, which includes statements made by those arrested in Madhya Pradesh.

Nagori's interrogation gives a clearer picture, the sources added. Based on his interrogation, the IB said SIMI had split into two factions -- the moderate Misba-ul-Islam faction and the Nagori faction. According to Nagori, of SIMI's 400 members, the bulk, around 300 members, have joined his faction.
