Earlier, Delhi Police Commissioner BS Bassi had said that Sunanda Pushkar’s death was not a natural one.
In January last year, Delhi Police had registered a case of murder in connection with the death of Sunanda.
An AIIMS medical board had found poisoning as reason for her death following which the police had sent her viscera samples to an FBI lab in Washington in 2015.
Sunanda was found dead inside her suite at a five-star hotel in New Delhi in January 2014. The SIT is likely to file the final report in the case by 28th February.
