Khaleel Brohi, the alleged mastermind of the attack in his confessional statement revealed that he used to work with Aslam Punjabi group of banned organization Lashkar-e-Jhangvi (LeJ).
Khaleel confessed that his group planted the bomb at the Shrine of Hajan Shah Mari Waro and showed the investigative team the spot where the bomb was planted.
The other suspect Shair Ali Brohi’s brother Pir Baskhsh Brohi was involved in the suicide bombing on former MNA Doctor Ibrahim Ali Jatoi. The attack killed a Station House Officer (S.H.O) and four other people.
The information obtained from the two suspects led intelligence agencies to the discovery of a bomb making factory in Durrani Goth. A diary with the bomb making procedure and a huge amount of explosive material, ball bearing and nuts were recovered from the factory.
Sources say that the explosive was enough to make twenty suicide jackets.
Both Khaleel and Pir Bakhsh Brohi belong to Dera Murad Jamali area of Balochistan province.
