New Delhi: Sunanda Pushkar's son Shiv Menon was today questioned by the SIT in connection with her mysterious death even as the police are likely to question former Union minister Shashi Tharoor and his domestic help again to reconstruct the chain of events in the case.

Menon reached the Special Investigation Team (SIT) office in South Delhi's Vasant Kunj at around 1.20 PM this afternoon and the questioning continued till late in the evening. Police sources said that Menon was asked how the relationship was between Tharoor and Sunanda.

Sources also said that police will question almost all the people whom they think are important for a solution to the case. "After quizzing Menon, we are considering questioning Tharoor and (his domestic help) Narayan Singh again to reconstruct the theory," said a senior police official.

 Meanwhile, Police Commissioner BS Bassi said, "Tharoor, Narayan and some workers who were around are also included in the case because some new things have come to light now... That's why there would be a need for questioning again. Whenever it is required, we will be calling them for questioning."

Bassi said that police may hold talks with others as well whom they feel is necessary to approach. "We will also be holding talks with the additional people whom we feel are necessary (to the solution of the case). Those whom we feel we have to confront on the basis of evidence, we will confront them too... We need to talk to people who were present there when Sunanda Pushkar died," Bassi said.

Asked if police will call Subramanian Swamy for questioning, the police commissioner said, "I wouldn't want to close any option... if the SIT feels, they will surely call him (Swamy). Until the SIT takes a decision on this, it won't be right for me to speculate on anything." Bassi also said that there are some exhibits about which police want to get an opinion from abroad. He added that there are also some analyses that the police want done and they would soon send certain exhibits abroad towards that end.

The police team probing the case has questioned at least 15 people in this connection.  Congress MP Shashi Tharoor and his staff members and close friends were among those quizzed by Delhi Police. Former Samajwadi Party leader Amar Singh and senior journalist Nalini Singh, too, have been questioned by police. 52-year-old Sunanda was found dead in her suite at a five- star hotel in south Delhi on the night of January 17, 2014, a day after she was involved in a spat with Pakistani journalist Mehr Tarar on micro-blogging website twitter over the latter's alleged affair with Tharoor. Police had last month filed a murder case in their pursuit of the matter.
