MUMBAI, INDIA - AUGUST 6: (File photo) Indian politician Shashi Tharoor with his wife Sunanda Pushkar Tharoor at Lalit Doshi Memorial Award 2009-2010 at Y.B. Chavan Auditorium, Churchgate on August 6, 2010 in Mumbai, India. Sunanda Pushkar, the 52-year-old industrialist wife of Union HRD minister Shashi Tharoor was found dead on Friday at a seven-star hotel where the couple had checked in together a day earlier, the police said. News of her death emerged late in the evening, coming within two days of her Twitter spat with a Pakistani journalist, Mehr Tarar, over an alleged affair with the minister. Pushkar, who has business interests in Dubai and was the Congress minister’s third wife, was found dead in the bedroom of The Leela Palace suite number 345 around 8.15pm. Mehr Tarar, a columnist with Pakistan’s Daily Times, reacted to the news of Pushkar’s death in two consecutive tweets: What the hell. Sunanda. Oh my God and I just woke up and read this. Im absolutely shocked. This is too awful for words. So tragic I dont know what to say. Rest in peace, Sunanda. (Photo by Hemant Padalkar/Hindustan Times via Getty Images)

The Federal Bureau of Investigation has ruled out the death of Sunanda Pushkar, deceased wife of MP Shashi Tharoor, by polonium or other radioactive substances according to the Times of India.

Sunanda Pushkar's viscera samples were sent to US after doctors at the All India Institute of Medical Sciences--among India's premier medical institutions--said that Indian labs lacked facilities to identify the poison which caused her death. The Delhi Police had put together a special team to probe Pushkar's death who was found dead in a luxury hotel in Delhi in January 2014.

According to The Hindu, the reports from the FBI suggest that the radioactive substance present in the body had not reached toxic levels, which could have resulted in death. The reports were sent to Indian authorities nearly nine months after the samples were first sent to the US-based lab.

Delhi Police Commissioner BS Bassi confirmed receipt of the reports to The Hindu and said that "some facts related to the case" would be disclosed soon.

The name of the poison, which the Delhi Police say was also disclosed in the FBI report, would now lead the Special Investigating Team, which is probing the alleged murder, to how it was procured and administered into Sunanda's body.
