According to Bhat, Delhi Police has hardly made any headway even after five months of the death to determine whether it was a murder or a suicide and case needed to be shifted to the CBI.   

Meanwhile, Delhi Police commissioner, B.S. Bassi had a meeting with the home minister Rajnath Singh to brief him on the progress. It seems that Delhi police will speed up their investigations. In case, they do not crack the case within a few weeks, there seems to be every likelihood of a CBI probe being instituted.

It is learned that the BJP leader Subramanian Swamy was also planning to approach the court for a court-monitored investigation in the case.

It may be recalled Sunanda Pushkar (1964-2014) had met Shashi Tharoor at a party organised by another tycoon Sunny Varkey in Dubai in 2007 that turned into friendship and closeness between the two. They got married in 2010 in a Malayali wedding ceremony, after Tharoor got elected to the Indian Parliament.  This was the third marriage for both of them.

Shortly before her mysterious death in a Delhi hotel in 2014, a misunderstanding between the couple was reported in the media. It was on July 1 that controversy over her death got into the limelight once again and further deepened with Doctor Sudhir Gupta of AIIMS claiming that he was pressurized to give a false report in the death case of Pushkar.
