Nov 11 (Agencies): Former Union Minister Shashi Tharoor's wife Sunanda Pushkar didn't die because of polonium or any other radioactive substance, the FBI has emailed to the Delhi police.
According to media reports, the Federal Bureau of Investigation (FBI) disclosed that the radiation in Pushkar’s viscera samples was within permissible levels and didn't cause her death.
Sunanda's viscera samples were sent to the FBI lab in Washington in February after the doctors at the All India Institute of Medical Sciences in Delhi stated that the poison could not be detected in Indian labs.
The 51-year-old was found dead at the luxurious Leela Hotel in Delhi in January 2014.
Earlier, her death was considered as a case of suicide but later, the Delhi Police claimed that Pushkar was poisoned to death by unknown persons.
