The Sub-Divisional Magistrate, probing the death of Sunanda Pushkar, on Tuesday directed the police to investigate the case thoroughly including the murder and suicide angles after he categorically pin-pointed poisoning as the reason behind the sensational demise.

Significantly, Alok Sharma, the SDM in his report, said no family member of Sunanda doubted any foul play in her death, the sources said.

Doctors at AIIMS who conducted autopsy on Sunanda had said her death was “sudden and unnatural” and it was caused by “drug overdose” which in other words could be called drug poisoning.

52-year-old Sunanda was found dead in a 5-star hotel in South Delhi on Friday night, a day after her twitter spat with Pakistani journalist Mehr Tarar over an alleged affair with Tharoor.

AIIMS sources said the autopsy report submitted to the SDM mentioned about over a dozen injury marks on both hands of Sunanda and a minor bruise on her left cheek which could be due to use of “blunt force”.

The report, however, ruled out death due to the injuries.

The autopsy report also said no food samples were found in Sunanda’s stomach which according to doctors suggested that “she had not been eating”.

Police sources said two strips of anti-depressant drug alprozalem, commonly known as alprax, were found in the hotel suite where she was found dead.

Sunanda case: Shinde says he has ordered expeditious probe

Home Minister Sushilkumar Shinde has asked the police to conduct an expeditious probe into the death of Sunanda Pushkar, wife of Union minister Shashi Tharoor.

“He (Tharoor) has written to me and sought an expeditious probe. I have already talked to the persons concerned and they are doing it,” he told reporters on the sidelines of a function in New Delhi on Monday.

Tharoor, Minister of State for HRD, had yesterday written a letter to the Home Minister offering his full cooperation in the probe into the death of his 52-year-old wife Sunanda, saying he was “horrified to read the reckless speculation rampant” in the media.

In the letter, Tharoor, 57, had said the relevant authorities be asked to expedite the investigation and come to a rapid conclusion so that the truth emerges at the earliest regarding Sunanda who was found dead in a luxury hotel in New Delhi on Friday evening.
