The Central Bureau of Investigation arrested brothers Sagar Sonkar and Saheb Sonkar on Friday in connection with the murder of Chandranath Rath [1].
The arrests signal a potential escalation in political violence within West Bengal, as investigators now seek to determine if the killing was orchestrated by political rivals.
Rath served as a close aide to West Bengal Chief Minister Suvendu Adhikari [1]. According to investigators, the brothers were involved in planning and executing a contract killing to eliminate the official [2], [3].
Officials said the probe is currently focused on the conspiracy behind the attack. The CBI is investigating alleged links between the suspects and a functionary from a rival political party [4], [6].
Two suspects have been taken into custody as part of this effort [1]. The investigation continues to trace the chain of command, and the financial transactions that may have motivated the contract hit [3], [4].
West Bengal has seen a history of volatile political clashes, and this case highlights the continued risk to high-profile political aides. The CBI is working to uncover whether the suspects acted alone or as part of a wider network of political operatives [6].
“The CBI is investigating alleged links between the suspects and a functionary from a rival political party.”
The involvement of the CBI in a murder case involving a Chief Minister's aide suggests that local law enforcement may have been insufficient or that the political sensitivity of the case required a federal agency. By probing links to a rival party, the investigation could uncover systemic patterns of contract killings used as political tools in the region, potentially leading to further high-level arrests.
