In a dramatic twist to the Sunanda Pushkar death case, the Delhi Police confirmed on Tuesday that she was murdered, with the medical board calling her death 'unnatural'.

According to Times Now, Delhi Police commissioner BS Bassi has said that a case of murder will be registered soon.

A year after the death of MP Shashi Tharoor's wife, the Medical Board said that her death was 'unnatural' and was because of poisoning.

ANI quoted Bassi as saying, "Medical report says she was poisoned, oral or injected we do not know, it is being investigated."

"We have to investigate whether she poisoned herself or whether she was forcefully given poison," Bassi told the media.

"We are taking all necessary measures in the case. It is clear that Sunanda Pushkar's death was not natural," Bassi said and added, "The Post-mortem report does not say whether poison was taken or injected. Need to send samples abroad for further tests."

CNN-IBN reported that an FIR has been registered under Section 302 (murder) and other relevant sections. "The FIR is not against any particular person," Bassi said.

"We can only say which substance caused the poisoning after further investigation," Bassi said.

The police also said that Shashi Tharoor will be questioned.

Pushkar was found dead in her hotel room number 345 of the Leela Palace in New Delhi's Chanakyapuri. Her body was found by her husband Shashi Tharoor.
