The Central Bureau of Investigation (CBI) has arrested Vinay Rai, the fifth individual implicated in the murder of Chandranath Rath, who served as the personal assistant to West Bengal Chief Minister Suvendu Adhikari. Rath, a former Indian Air Force personnel, was shot near Madhyamgram on May 6 and succumbed to his injuries in the hospital. The CBI, working with the Muzaffarnagar Police, also apprehended Rajkumar, identified as the main shooter, in Muzaffarnagar, Uttar Pradesh. He is set to be presented before a Special CBI Court in Kolkata. The investigation was prompted by a complaint from Rath's brother, which led to the CBI taking over the case from the West Bengal Police. The agency has registered a First Information Report (FIR) citing organized crime and conspiracy, invoking various sections of the Bharatiya Nyaya Sanhita, 2023, and the Arms Act. Additionally, three other suspects have been remanded to police custody until May 24, with the prosecution seeking to add charges related to evidence destruction. Public Prosecutor Advocate Bivas Chatterjee confirmed that the court has accepted these additional charges.
