The ministry has conceded a litany of flaws in India's terror investigations and emergency response in a background paper accessed by NDTV, which will be circulated at the Indo-US Homeland Security dialogue on Wednesday.
The Hyderabad twin bomb attack would have joined the long list of unsolved cases, the ministry admits, had it not been for the chance arrest of Indian Mujahideen co-founder Yasin Bhatkal in August. Bhatkal has allegedly detailed how the bombings were carried out.
The home ministry says in the first few hours after the attack, competition between agencies like the National Investigation Agency (NIA), the state Criminal Investigation Department (CID) and the state special force or Octopus commandos ensured no one shared information or had a complete picture of the attack.
The ministry also reveals that some of the injured people who died in hospital may have been saved had their transfer and treatment been prompt. Traffic jams across the city delayed ambulances, leaving rescue workers to deploy state-run buses to ferry the injured to the hospital.
Visits by politicians also hampered blast investigations, the home ministry says. "Adequate bandobast (arrangements) had to be made for VVIPs visiting the blast site putting additional stress and strain on the police. Large crowds and the media disturbed the crime scene."
