Union minister Shashi Tharoor will be questioned by the Sub-Divisional Magistrate on Monday, in connection with the death of his wife Sunanda Pushkar.
Announcing Sunanda's preliminary autopsy result, doctors said on Friday that it was a case of "unnatural sudden death". Some injury marks were also found on her body, the nature of which cannot be revealed, the doctors said. However, they also ruled that those injures could not have led to her death.
The report of the post-mortem examination, which was filmed throughout, is likely to be submitted to the SDM after two or three days. Since the Sunanda-Tharoor marriage was less than seven years old, the SDM will probe the incident under IPC Section 176.
Sunanda, 52, who was seen getting increasingly frantic and upset over the past few days due to an alleged extra-marital affair between Tharoor and Pakistani journalist Mehr Tarar was found dead in Leela Palace hotel in Delhi.
She was in the headlines this week after she hacked into her husband's Twitter account and posted private messages between him and the woman who, she alleged, was 'stalking' him.
A spate of Twitter messages from Sunanda, criticising Tarar, went viral and she even alleged in a television interview on Thursday that Tarar was a Pakistani ISI agent, who was trying to ruin her marriage.
Meanwhile, a series of conspiracy theories have begun flooding the social media on how Sunanda died. While some suggest it could have been a case of sleeping pills overdose, a handful of Twitter members were seen discussing the possibility of the ISI's link to her death.
