The country's security agencies appeared to be working at 'cross-purposes' in the hours after the Dilshukhnagar blasts that killed 19 people in Hyderabad in 2013, according to a home ministry document prepared for the India-US Homeland Security Dialogue beginning Wednesday.
The document conceded there was no proper coordination between various investigation agencies including the NIA and the state CID, with each agency picking up evidence from the blast scenes and taking it.
"Each agencies wanted to single-handedly investigate the offence and detect the case," the background note prepared by the home ministry's Bureau for Police Research and Development for Wednesday's conference of police chiefs from India and US said.
"Each agency started picking up evidences from the scene. Information/evidence collected by various agencies (State/Central) were not shared with the local police or with each other," the note - that look up the response to the Dilsukhnagar blasts as a case study - said, conceding that the crime scene was disturbed as people started moving freely before the police could sanitise the area.
Two blasts in the crowded shopping area within 50 metres of each other had killed 19 people an injured another 126.
Security agencies had blamed the attack on the Indian Mujahideen but their first breakthrough came only after the arrest of IM co-founder Yasin Bhatkal who told investigators how they executed the blasts.
The home ministry analysis said an assistant commissioner of police-rank officer was tasked to protect the blast scene. But the crime scene was "largely disturbed" due to a crowd of curious onlookers, media persons and continuous visits of the VIPs.
