Bassi not revealing what really killed Sunanda Pushkar: Subramanian Swamy

New Delhi: Asserting that Congress leader Shashi Tharoor's wife Sunanda Pushkar was poisoned to death, BJP leader Subramanian Swamy on Saturday accused Delhi Police Commissioner BS Bassi of not revealing the exact chemical compound that was responsible for her death.

"Police Commissioner is not telling the media that the FBI found the presence of heart arrest injectable poison lidocaine in Sunanda body," Swamy tweeted.

After receiving the observations by the All India Institute Of Medical Science (AIIMS) in Pushkar's viscera report, Bassi yesterday confirmed that her death was due to 'unnatural' causes.

Speaking to the media here, he asserted that in the report by the FBI, it was said that none of the samples sent to them contained any radioactive material.

According to the AIIMS Panel, which is headed by Dr. Sudhir Gupta, the head of the Department of Forensics, Pushkar died after being poisoned by Polonimum-210 or Po-210, sources state.

The Delhi Police had submitted a 15-page Federal Bureau of Investigation (FBI) report to AIIMS Medical Board for further opinion.

Sunanda Pushkar, 51, was found dead at the Leela Hotel in New Delhi in January 2014.

Pushkar's viscera samples were sent to the FBI lab in Washington in February last year after a panel of doctors from AIIMS said that the alleged 'poison' could not be detected in Indian labs.
