The Central Bureau of Investigation on Tuesday arrested one more person accused of the murder of an aide to West Bengal Chief Minister Suvendu Adhikari, PTI quoted officials as saying.The officials said that Vinay Rai, a resident of Ghazipur in Uttar Pradesh, was arrested in Varanasi. Rai, who is the fifth person arrested for the killing, will be produced before a court in Kolkata.The aide, Chandranath Rath, had been shot dead near Kolkata on May 6. The CBI had taken over the investigation into his murder after a request from the state government.Rai’s arrest on Tuesday came a day after the CBI arrested another key accused, Raj Kumar Singh alias Raj Singh, from Muzaffarnagar in Uttar Pradesh. Earlier this month, three others were arrested in Bihar and Uttar Pradesh in connection with Rath’s killing.These men were identified as Vishal Srivastava, a resident of Bihar’s Buxar district, Mayank Mishra and Vicky Maurya. Mishra and Maurya are from Uttar Pradesh, officials said.Rath was killed amid widespread political violence in West Bengal after the Bharatiya Janata Party defeated the Trinamool Congress in the Assembly elections.He was travelling in a car to his home in Barasat when assailants on motorbikes intercepted the vehicle in the Madhyamgram area at about 10.20 pm. One of the suspects reportedly approached the car and fired three bullets at close range, it had been reported at the time.Rath, who was seated next to the driver, sustained several bullet injuries and was declared dead after being taken to hospital. His driver, Buddhadeb, was seriously injured.The motive for the murder was unclear.Rath had worked with Adhikari for several years and handled political coordination and organisational work. He had reportedly been associated with the BJP leader since 2018 and later became his executive assistant after Adhikari became Leader of the Opposition in West Bengal.Adhikari, who became the chief minister on May 9, was not with Rath at the time of the attack. The BJP leader alleged that it was a “pre-planned murder”.The Trinamool Congress had condemned Rath’s killing and expressed grief over the deaths of party workers in separate incidents of violence across the state. The party alleged that “BJP-backed miscreants” had been involved in post-poll unrest and called for a court-monitored CBI probe into the killing of Rath.Edited by Sneha.
