Bharatiya Janata Party (BJP) MP Subramanian Swamy on Saturday wrote to Home Minister Rajnath Singh seeking his intervention in setting up a Special Investigation Team (SIT) to take forward the probe into mysterious death of Sunanda Pushkar, wife of Congress leader Shashi Tharoor.
The BJP leader has been crying foul over the death of Pushkar.
Swamy has even alleged that the wife of the Congress leader was killed in a professional way.
Sunanda was found dead inside her suite at a five-star hotel here in January 2014, a day after she was involved in a spat with Pakistani journalist Mehr Tarar on Twitter over the latter's alleged affair with Tharoor, the Congress MP from Thiruvananthapuram.
Her viscera samples were sent to the FBI lab in Washington DC in February last year to determine the kind of poison that killed her after an AIIMS medical board identified poisoning as the reason behind her death.
The FBI had endorsed the AIIMS report on poisoning and also said that a "dangerous chemical" was present in her body that may have killed her.
Swamy had earlier written two letters - one in July, 2014 and another in December 2014 - to the Home Minister in this regard.
