Agencies Investigating the Delhi Blast Case

1. Delhi Police – Special Cell (Lead Agency)

• Primary agency responsible for the investigation
• Conducts arrests, custodial interrogation, and crime-scene reconstruction
• Identifies the conspiracy chain—planners, executors, and facilitators
• Analyzes digital evidence (mobile phones, call data records, chats, GPS)
• Prepares and files the charge sheet before the court

2. Intelligence Bureau (IB) – Intelligence Support

• Provides real-time intelligence inputs
• Tracks radicalisation, sleeper cells, and extremist modules
• Identifies foreign links, cross-border coordination, and funding channels
• Assists in preventive surveillance to avert future attacks

3. Forensic Science Laboratory (FSL) – Technical & Scientific Role

• Examines explosive materials and blast residue
• Conducts digital forensics on seized electronic devices
• Matches forensic evidence with accused persons
• Strengthens prosecution by providing scientific and legally admissible proof

4. National Investigation Agency (NIA) – Conditional Takeover

• Can take over the case if:
• Inter-state terror networks are involved
• International terrorism links are established
• Offences fall under UAPA (scheduled offences)
• Ensures uniform national-level investigation of terrorism cases

Why Is a Multi-Agency Approach Important for Internal Security?

1. Complex Nature of Modern Terrorism

• Terror attacks involve multiple layers—planning, logistics, funding, execution
• No single agency possesses all required intelligence, legal, and technical capacity

2. Intelligence Sharing and Coordination

• Combines ground-level policing with strategic intelligence
• Reduces intelligence gaps and duplication of effort
• Enables faster identification of networks rather than isolated individuals

3. Stronger Evidence and Conviction Rates

• Forensic + digital + human intelligence ensures watertight cases
• Improves chances of conviction and judicial credibility

4. Preventive Internal Security

• Helps identify sleeper cells and future threats
• Strengthens early-warning systems
• Shifts focus from reaction to prevention and disruption

5. Federal and National Security Balance

• State police handle ground realities
• Central agencies address inter-state and international dimensions
• Ensures cooperative federalism in internal security

6. Policy and Structural Strengthening

• Improves Standard Operating Procedures (SOPs)
• Enhances multi-agency intelligence mechanism (MAIM)
• Supports capacity building in cyber, forensic, and counter-terrorism domains

Legal Framework Supporting Multi-Agency Action

1. Bharatiya Nyaya Sanhita (BNS)
2. Unlawful Activities (Prevention) Act – UAPA
3. Laws on electronic and digital evidence

Challenges in Multi-Agency Investigations

1. Jurisdictional overlaps
2. Information silos
3. Coordination delays
