Sunanda Pushkar murder: Delhi Police might be under pressure to 'harass' Tharoor, says Congress

New Delhi: With the Delhi Police confirming that Sunanda Pushkar's death was due to 'unnatural' causes, the Congress Party on Saturday said that the B.S. Bassi-led Delhi Police might have been under pressure to harass Shashi Tharror unnecessarily.

"It is for the Delhi Police to see whether the death of Sunanda Pushkar was natural or not. The whole thing seems to be a very big mess. Sometimes evidences say something else and sometimes something else," Congress leader Sandeep Dikshit told ANI.

"I only hope that there is nothing else in this case. Tharoor is a very strong, powerful Congress leader and sometimes news comes that this case is being used to harass him unnecessarily and perhaps pressure may be put on the Delhi Police to do things, which the evidence may not be pointing at," he added.

Meanwhile, asserting that Shashi Tharoor's wife was poisoned to death, BJP leader Subramanian Swamy on Saturday accused 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 Sunanda's 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.
