Junior HRD Minister Shashi Tharoor's wife Sunanda Pushkar, who died Friday night, had "injury marks" on her body and it is a "case of unnatural, sudden death", a doctor who conducted the post-mortem said.
"We can say that it is a case of unnatural sudden death. There were certain injury marks on the body but we can't divulge details at this point," said Sudhir Gupta, one of the three doctors who performed the autopsy at the All India Institute of Medical Sciences (AIIMS).
"We have retrieved some biological samples and have videographed the whole procedure and have taken photos. We will conclude our report and opinion in a couple of days," he added.
Sunanda Pushkar was found dead under mysterious circumstances in her room at The Leela Palace hotel in south Delhi Friday.
Her death came barely 24 hours after she and Shashi Tharoor declared they were "happily married" following public airing of tweets that hinted at an extra-marital relationship and alleged involvement of a Pakistani woman.
Tharoor, who complained of chest pain, was admitted in the same hospital few hours after Pushkar's death. He was discharged in the afternoon.
He accompanied Pushkar's body in the ambulance to their residence at 97, Lodhi Estate.
