The Central Bureau of Investigation (CBI) takes over the murder investigation of Chandranath Rath, the personal assistant of West Bengal Chief Minister Suvendu Adhikari. Multiple outlets report that the CBI assumes control of the case from West Bengal Police after a request from the state government. The CBI forms a seven-member Special Investigation Team (SIT) led by a DIG-rank officer, with officers drawn from multiple states and described as experienced. The CBI’s team investigates the killing as part of a wider inquiry into possible motives and linkages. Business Standard and other reports say the CBI re-registers the FIR earlier lodged by police and begins examining multiple angles, including potential interstate criminal links and conspiracy. Times of India adds that the CBI files an FIR and holds an internal meeting at CBI headquarters to review developments and seek remand of arrested suspects. NDTV reports that a key accused is arrested from Uttar Pradesh. The CBI is expected to arrive in the state and proceed with an investigation aimed at determining the circumstances and any larger conspiracy behind the murder.
