Injury marks were also found on the body of 52-year-old Pushkar, who was last night found dead in mysterious circumstances in luxury Leela Palace hotel in South Delhi.
    
The head of the three-member panel of doctors that conducted the autopsy on Pushkar, said, "We have conducted the postmortem examination... It is a case of sudden, unnatural death" but ruled out poisoning.
    
However, he said the team has preserved certain "biological samples for toxicological analysis as well as visco-pathological examination."
    
"We have completed the whole procedure. Samples for toxicological analysis means ruling out any poison. Some pathology of the heart has been preserved by us," he said.
    
Pushkar was found dead in her suite at the hotel and the body was shifted to AIIMS at around 3:30 AM for post-mortem.
    
Police is also expected to record statement of Tharoor, who was admitted to AIIMS following complaints of chest pain and was discharged later.
    
Pushkar and Tharoor were at the centre of a raging controversy when reports emerged that she was upset over reported text and tweet messages between her husband and Mehr Tarar, a Pakistani journalist.

Hours after his wife was found dead, the 57-year-old Union Minister of State for Human Resources was admitted to AIIMS after complaining of chest pain. Sudhir Gupta, Head of Forensic Sciences Department at AIIMS said the post-mortem is being videographed to ensure transparency in the procedure.
    
Pushkar was found dead in her suite at the Leela Palace hotel on Friday evening and the body was shifted to AIIMS at around 3:30 am for post-mortem. Tharoor was admitted to the ICU of the cardiothoracic centre of the AIIMS and a number of investigations including ECG were carried out on him. The Minister was discharged at around 12 noon.
    
Doctors said he was brought to the hospital with a "cardiac condition" but he is stable now. Continuing investigation, police questioned a number of hotel staff and checked the CCTV footage of the lobby of the third floor of the luxury hotel where she was staying.
    
Sources in police said call details record as well as Pushkar's tweets were being checked. Pushkar and Tharoor had checked into the hotel on Thursday as their home was being painted. A number of hotel staff, including those who had gone to her suite, were being questioned to corroborate the version of Tharoor and his staff.
    
Pushkar and Tharoor were at the centre of a raging controversy when reports emerged that she was upset over reported text and tweet messages between her husband and Mehr Tarar, a Pakistani journalist.
    
Delhi Police spokesman Rajan Bhagat said inquest proceedings have been initiated by the sub-divisional magistrate of the area. Any death within seven years of marriage is legally required to be investigated by the sub-divisional magistrate.

Gupta said the post-mortem will take at least two hours and after that the findings will be scrutinised and, if needed to be shared, will be given to the media. Pushkar and Tharoor had checked into the hotel on Thursday as their home was being painted.
    
A joint statement from the couple on Thursday said that they were "happily married" but distressed by "some unauthorized tweets".

Pushkar had accused Tarar of "stalking" her husband and trying to "break" her marriage when she was away for medical treatment.


    
She had told couple of newspapers that she was considering divorce from Tharoor in the wake of the alleged extra-marital affair. The Pakistani journalist rubbished the charges of having any relationship with Tharoor, who is Congress Lok Sabha MP from Thiruvananthapuram.
    
After Pushkar's death Tarar had tweeted: "I just woke up and read this. I'm absolutely shocked. This is too awful for words. So tragic I don't know what to say. Rest in peace, Sunanda."
    
Asked about the cause of death, Delhi Police Spokesperson Rajan Bhagat had said there is no apparent sign which can reveal that.
