Sunanda murder case: Shashi Tharoor to be questioned again by SIT today

Delhi Police Commissioner BS Bassi has said that former minister Shashi Tharoor will be questioned once again no Thursday by the Special Investigation Team (SIT) in connection with his wife Sunanda Pushkar's murder.

Tharoor's domestic help Narain Singh will also be reportedly questioned by the SIT today.

"The investigation is on. We will call him (Shashi Tharoor) tomorrow to gather some more details," said Bassi.

"We cannot tell the time. It will be in accordance with the investigation team," he added.

Earlier in January, Tharoor was interrogated at the Vasant Vihar police station in South Delhi. He was asked over 50 questions by a team of four officers in the first of three likely rounds of interrogation.

The police had earlier in January said that based on available evidence, Sunanda Pushkar, 51, was poisoned. A case of murder was registered on January 6.

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

She 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, Mehr 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."
