Top Indian Mujahideen leader Yasin Bhatkal was flown to Darbhanga in Bihar on Saturday to retrace over the past decade the creation of the deadly Bihar module.
Meanwhile, parts of a pressure cooker and a black bag used in the February 21 Dilsukhnagar blasts were seized this month from Abdullanagar, on the outskirts of Hyderabad, at the behest of fellow IM leader Assadulla Akhtar alias Haddi.
Top government sources said Yasin had created a module of around 12 youth from Darbhanga, Samastipur, Madhubani and Purnia after befriending Fasih Mehmood at Anjuman College in Bhatkal, Karnataka, in 2002. While the radicalised Mehmood left to work in Saudi Arabia, Yasin motivated the north Bihar boys into jihad against India. Yasin was taken to Mohalla Chakjura, in the Lahariya Sarai police station area in Darbhanga, to identify the residence he shared with another IM cadre Danish.
Yasin's Bihar module comprised Tehsin Akhtar alias Monu of Samastipur, late Mohammed Qateel Siddiqui of Darbhanga, Gauhar Azzi Khomani of Darbhanga, Gayur Ahmad Jamali of Madhubani, Abdur Rehman of Dharbhanga, Mohammed Tariq Hasan of Purnia, Mohammed Kafil of Darbhanga, Asadullah Rehman of Darbhanga, and Mohammed Kafil of Darbhanga.
Though these indoctrinated youth provided logistics and shelter to Yasin, many weren't directly involved in planting the bombs. "The whole idea to take Yasin was to retrace the radicalisation in Bihar by IM and identify other suspects for filing of charge sheets," said a senior official.
Similarly, around September 6-7, Haddi was flown by an NIA team to Mangalore and Hyderabad for identifying the hideout where he and Pakistani national Waqas made explosive devices.
The agency recovered 75 Gasio (Chinese made) watches and 12 timer circuit boards from the Mangalore flat which Waqas and Tehsim Akhtar fled on August 30 after hearing of Yasin's arrest.
From Abdullapur in Hyderabad, the sleuths recovered parts of the pressure cooker used to make the Dilsukhnagar bombs and a black bag used for transporting the device.
Haddi and Tehsim Akhtar were identified as the main perpetrators of the Hyderabad blast as Yasin refused to participate despite instructions from Pakistani ISI handler Riyaz Bhatkal.
Yasin told his interrogators he wasn't convinced about targeting Hyderabad as it was a revenge for the hanging of 2001 Parliament attack convict Afzal Guru.
