On Monday, the Enforcement Directorate (ED) had conducted raids at 12 locations across the state in connection with the coal scam, including searches at offices and residential addresses of businessman Ganesh Bagadia and Sanjay Singh. The raids were conducted from Monday morning in Kolkata's Lake Town area, Garia, Konnagar's Kanaipur in Hoogly district, and North 24-Parganas in connection with the illegal trading of coal.
