Raj Singh, a resident of Anand Nagar in Ballia, Uttar Pradesh, was arrested on Sunday night in Ayodhya for his alleged involvement in the murder of Chandranath Rath, an aide to West Bengal Chief Minister Suvendu Adhikari. Rath was shot dead on May 6 in Madhyamgram, North 24 Parganas district, West Bengal. Singh is suspected of playing a role in the logistical planning of the murder, which investigators believe was executed by an organized interstate network. Singh had previously contested a local civic election and is known to have political connections in Uttar Pradesh. His arrest followed a multi-state operation by the special investigation team (SIT) of the West Bengal Police, which tracked him using technical surveillance and intelligence inputs. Singh's family has denied the allegations, with his mother demanding a Central Bureau of Investigation (CBI) inquiry into the case. The investigation continues, focusing on the broader network involved in the murder, including the use of fake number plates and coordinated movements.
