The investigations into the blast at the CID centre have revealed that terrorists used 500 kilogrammes of TNT in the attack.
Official sources revealed the attack was carried out by four terrorists in two minutes and seventeen seconds. The terrorists had thrown a hand grenade at a check post to clear the way for a white pick-up truck, which was used in the attack.
The attack on the Sindh police’s main investigation agency, the Crime Investigation Department (CID) building, near PIDC, had killed at least 16 people and injured more than 140. A coordinated gun and car bomb suicide attack had been carried out in the back alleys of what is referred to as the highest security zone in the city – mere metres away from the Sindh Chief Minister House and in the backyard of the most heavily guarded installations in the city.
