Sunanda Pushkar case: Tharoor's statement to be examined

"We have spoken to him about the background. We have also spoken about what happened on that day and also certain things which have been said otherwise in the media. Since he had come at around 7.30 so we will analyse whatever he told us in about three-three and a half hour and then take further necessary action," said Bassi.

"He was co-operative. Now, we will analyse and take a call. If any other further questioning is required, if yes, then when. While examining this case, we are taking it with an open mind. We are trying to ascertain what happened," he added.

Tharoor was interrogated at the Vasant Vihar police station in South Delhi last evening.

Sunanda Pushkar was found dead in the five-star Leela Hotel in Delhi on January 17, 2014.

According to media reports, Tharoor was asked over 50 questions by a team of four officers in the first of three likely rounds of interrogation.

Earlier this month, the police had said that based on available evidence, Sunanda Pushkar, 51, was poisoned.

A case of murder was registered on January 6.

Sunanda Pushkar was married to Tharoor for a little less than four years. It was the third marriage for both. Before her death, Pushkar had publicly accused Tharoor of having an affair with a Pakistani journalist Meher Tarar.

Initially, her death was debated as a possible suicide for months, and it was only this month, that a murder theory began to be considered seriously after doctors at the All India Institute of Medical Sciences (AIIMS) maintained that her demise was unnatural.

Tharoor has been demanding that the investigation must be "free of political pressure or a pre-determined outcome."
