The National Investigation Agency (NIA) Thursday registered a case in the February 21 twin blasts at Dilsukhnagar in Hyderabad,in which 17 people were killed and 50 injured. The agency also formed a special investigation team (SIT),headed by an IG,with officials from Delhi and Hyderabad.
Investigators suspect the role of the Indian Mujahideen (IM) in the blasts,due to similarities in the method and nature of bombs. Two IM suspects arrested last year have claimed that they conducted a recce of Dilsukhnagar on the instructions of IM chief Riyaz Bhatkal.
However,officials have not been able to identify the group behind the explosions. No group has claimed responsibility so far,because of which intelligence agencies suspect that absconding IM members Yasin Bhatkal,Asadullah Akhtar and others may have carried out the attack.
A special court had earlier issued non-bailable warrants against IM founder Riyaz Bhatkal,Iqbal Bhatkal,Mohsim Chaudhary,Amir Reza Khan,Dr Shahnawaz Alam,Asadullah Akhtar,Ariz Khan,Mohd Khalid,Mirza Shadaab Beg and Mohd Sajid.
