The investigation into the crude bomb attack in front of AKG Centre appeared to gather pace amidst rampant griping about an alleged law enforcement failure.
Forensic experts gathered evidence from the explosion scene. A police official said the throw-down type country-made explosive device that detonates on impact appeared to contain no lethal shrapnel.
The explosive charge seemed fashioned from low-grade powder used in firecrackers. The official called it a crude "flash-bang" device that could stun but not injure seriously. It could also cause burns.
