Days before the final phase of the 2026 West Bengal assembly elections, investigators are piecing together what could be a larger, organised ecosystem behind a major explosives haul in Bhangar which may have been intended to trigger fear, violence and electoral disruption.

Top sources in the National Investigation Agency (NIA) told CNN-News18 that the focus is no longer just on the seizure itself, but on who funded, supplied and protected the stockpile.

Officials confirmed the recovery of 79 ready crude bombs, 3.37 kg of gunpowder, 1.61 kg of sulphur, and other explosive components. Investigators say the volume and readiness of the material point to planned deployment, not casual storage. “The intention appears to be to endanger lives and property and create fear and terror," the sources told CNN-News18.

The investigation has now widened into what officials describe as a multi-layered network probe, focusing on financial trails where NIA is examining transactions, funding routes, and possible sponsors behind the procurement of explosives; supply chains to trace the origin of chemicals, gunpowder, roll caps and detonator components; call records to identify handlers, middlemen and local operatives; and whether such a large cache could exist without local patronage.

The seizure took place just days before polling in Bhangar, a constituency going to vote in the final phase on April 29. Investigators believe the explosives could have been used during elections for booth capturing, voter intimidation, political clashes, and area domination. The timing has heightened concerns about attempts to influence the electoral process.

Bhangar, on the outskirts of Kolkata, has a long record of crude bomb usage in political clashes. The area has frequently seen inter-party violence, turf battles, and use of locally made explosives as tools of intimidation. Such incidents have often involved rivalries between parties like the Trinamool Congress and the Indian Secular Front.

Officials say what sets this case apart is not just the presence of explosives but the scale and possible intent. The NIA is treating it as a scheduled offence under the NIA Act, probing whether the stockpile was part of a broader plan to create fear and disrupt democratic processes.
