Rath, 41, a former Indian Air Force soldier, was shot dead at close range inside his SUV while returning home in Madhyamgram area of North 24 Parganas district on the night of May 6, two days after the BJP came to power in the state, ousting the Mamata Banerjee-led TMC government after 15 years. His driver Buddhadeb Bera, who was also shot, was admitted to a private hospital in Kolkata; A third person, Minto, was not injured. An investigating officer, requesting anonymity, said: “An investigation is underway to trace those who hired these killers. The motive will emerge once they are arrested.”
On the night of the murder, the attackers chased Rath’s car for about seven kilometers before forcefully stopping his car. Rath was shot five times and died instantly. Berra was shot three times. Soon after the crime, Adhikari alleged that Rath was killed because of his close connections. BJP leaders across the country blamed the TMC for the murder. The Transitional Military Council, in turn, demanded an investigation from the Central Bank of Iraq.
