New Delhi, Jan 23 (IANS): Senior journalist Nalini Singh was questioned here in connection with the murder case of Sunanda Pushkar, Congress MP Shashi Tharoor's wife, police said Friday.

Singh was called by the probe team led by Deputy Commissioner of Police Prem Nath at Sarojini Nagar police station, where she was questioned for over an hour.

Singh told IANS: "I met them (police) for about 80 minutes. This was my first meeting with the police."

"Police asked me the sequence of my talk with Pushkar, before her death. They also asked the IPL (Indian Premiere League) angle as well," Singh said.

"I don't know what she wanted to say. But she wanted to speak about the IPL," the senior journalist added.

"To understand background of the case, the probing team is calling people who are connected to it," said Police Commissioner B.S. Bassi.

On the question of possibility of roping the Economic Offense Wing (EOW) into the case, Bassi said: "For understanding the background, if it is required, will do that."

On Thursday, the investigation team questioned another journalist, television anchor Rahul Kanwal of Headlines Today, to whom Pushkar had wanted to give an interview on certain undisclosed issue.

Later, Kanwal posted the contents of his talk with police on social media, stating Pushkar was keen to give an interview.

"On January 16, when the spat between Shashi Tharoor and Sunanda splashed all over the news channels, I reached out to Sunanda asking her if she was keen on doing an interview to talk about the 'IPL scam' she had been referring to in her tweets," Kanwal wrote in his Facebook account.

Both the journalists were questioned soon after Bassi told media Thursday that they would take the help of those journalists who had talked to Pushkar before her death to corroborate the sequence of events.

Pushkar was found dead in a luxury hotel's room here Jan 17, 2014. Police said she was poisoned. A murder case was registered by the police against unknown people Jan 1 this year.
