New Delhi: Delhi Police's SIT, probing the death of Sunanda Pushkar, on Thursday questioned the crew of a flight from Thiruvananthapuram to Delhi in which former Union minister Shashi Tharoor and his wife had allegedly fought on January 15 last year.
The SIT may also question a senior Congress leader, who was on the same flight, about what was the fight all about and what triggered it, said a police official associated with the probe.
"The members of the flight's crew were also questioned on these lines," the official said.
During his questioning, Tharoor's domestic help Narayan Singh had told police that after landing at Delhi, Pushkar had called their family friend Sunil Trakru who had taken her to the five star hotel where she was found dead later.
Earlier in the day, Delhi Police Commissioner B S Bassi today said that the SIT probe is on at full swing.
Some of those questioned in the case so far include Narayan Singh, Tharoor's family friend Sanjay Dewan, the hotel doctor who pronounced her dead, hotel's staff including its manager.
The official also said that police will question in a day or two a woman journalist with whom Sunanda had spoken before her death and Tharoor's PS Abhinav Kumar who had informed the then SHO of Sarojini Nagar police station about the death.
After Tharoor alleged police torture on one of his aides for "getting a confession" that he along with the Congress MP killed Sunanda, the SIT is taking precautions before questioning anybody in the case.
"People are contacted late in the night that they have to come for questioning tomorrow. They are also instructed not to inform anybody, especially media about it.
"Police also gets a medical examination done of the person before questioning him or her so that any allegation of torture can be ruled out," the official said.
"They are called at a spot from where they are taken to a different location. They are not allowed to use mobile phones and the SIT operation shifts base everyday," he added.
51-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 over the latter's alleged affair with Tharoor.
