Congress MP Shashi Tharoor's wife Sunanda was found dead at a five-star hotel in Delhi

South District police investigating the death of Sunanda Pushkar, the wife of former Union minister Shashi Tharoor, have learned that three people with fake passports were staying in the Leela Palace Hotel where she died from January 13 to January 18.

Investigators are now trying to uncover details of these three people.

A team of three police officers, including an ACP rank officer, is preparing to go to Dubai to get some more details about Sunanda. An officer in the investigating team told Mail Today that the south district police have started their probe.

After recovering the bed sheet and carpet on which fluid marks were found and broken glass from suite number 345 of the hotel, the police examined the visitors’ book.

“After scanning the visitors’ book, police came to know that three people were staying in the Leela Palace Hotel from January 13 to January 18 after submitting forged passport details,” the officer said.

He added that there are now no authentic details about these three because they had reportedly told the hotel staff that they were from a foreign country.

Sources said that a special team from the south district is also coordinating with the foreign regional registration office (FRRO), which comes under the Intelligence Bureau.

The Delhi Police are also considering sending the viscera samples linked to Sunanda to forensic laboratories abroad to determine the type of poison suspected to have caused her death.

The AIIMS medical board had, in its second report submitted to the police, confirmed poisoning as the reason behind her death - but did not mention the type of poison.

The board had listed some kinds of poison, many of which were radioactive isotopes that cannot be detected by labs in India.

Three mobile phones and a laptop belonging to Sunanda have already been sent to a forensic laboratory in Gandhinagar, Gujarat, for investigation to check whether anything was deleted from the gadgets after her death.
