The US Federal Bureau of Investigation (FBI) has found traces of an anti-anxiety drug in the body of socialite Sunanda Pushkar, police sources said on Friday, which corroborates earlier findings of the All India Institute of Medical Sciences (AIIMS).
An 11-page report analysing the FBI’s conclusions has been submitted to Delhi Police probing the case, police commissioner BS Bassi said on Friday, adding that the high-profile case will be now taken to the logical conclusion.
Besides traces of the antianxiety drug Alphrax, the FBI lab has also found an anesthetic drug ‘Lidocaine Gel’ in the viscera of Pushkar, found dead in a fivestar hotel in Delhi on the night of January 17, 2014, sources added.
Samples of the viscera were sent to an FBI lab in Washington after the Central Forensic Science Laboratory (CFSL) ruled out the presence of the anti-depressant drug Alphrax in her body.
Two used Alphrax strips were recovered from the crime scene and was used as circumstantial evidence in the high-profile case.
The body of Pushkar, 51, was recovered a day after her spat with Pakistani journalist Mehr Tarar on Twitter over her alleged affair with Tharoor.
In their statement to police, Pushkar’s doctors had also denied prescribing the drug to her.
In January last year, police had claimed that Pushkar was poisoned, and registered a murder case against unknown persons.
The sources said the FBI lab report states that radiation levels in Pushkar’s viscera samples were within permissible levels and could not have caused her death.
The AIIMS report, however, only upholds the findings of their initial autopsy report submitted on January 20, 2014, instead of giving out an analysis of the report submitted by FBI, the sources said.
“In its autopsy report, AIIMS had mentioned the cause of Pushkar’s death as poisoning; and the same has been confirmed and endorsed by the FBI,” said Dr Sudhir Gupta, the head of AIIMS’ forensic medicine department. He had headed the medical board that conducted Pushkar’s autopsy.
Bassi, meanwhile, held a meeting which was attended by the special investigation team (SIT) probing the case. Special commissioner of Delhi Police (law and order) Deepak Mishra briefed about all related angles in the case.
The investigators have so far conducted polygraph test on six persons, all prime witnesses in the case, including Tharoor’s domestic help Narayan Singh, driver Bajrangi and Sanjay Dewan, a close friend of the couple.
Tharoor was not subjected to the test but was questioned thrice.
Pushkar’s son Shiv Menon was also quizzed by the SIT on February 5 last year.
