The Central Bureau of Investigation (CBI) has taken over the probe into the murder of West Bengal Chief Minister Suvendu Adhikari's personal assistant Chandranath Rath.
According to the procedure, the CBI has re-registered the state police FIR as its own case and launched an independent probe to assess the evidence and allegations.
The case was earlier being investigated by the state police, who had arrested two men from Bihar and one from Uttar Pradesh in connection with the May 6 murder of Chandranath Rath.
Chandranath Rath, a 41-year-old former Indian Air Force serviceman, was shot dead from close range inside his SUV while returning home in the Madhyamgram area of Bengal's North 24 Parganas district.
The incident took place just two days after the BJP swept to power in the state, ousting the Mamata Banerjee-led TMC government after 15 years.
