Tharoor has already been examined by the SIT once. He was questioned by police on January 19 for around four hours at the office of Anti Auto Theft Squad (AATS) in South Delhi's Vasant Vihar.
"SIT is continuously probing the case. Whatever is necessary, they have been doing and I am sure that if they require to question anyone again, they will be doing that and they will be doing that soon," Bassi told reporters here when asked when would Tharoor be questioned again.
Sources said that SIT is likely to question the former Union minister this week as they got very "little time" with him on January 19.
They also said that as he was the "closest relative" of the deceased at the spot when she was found dead, he may be questioned several times as the SIT would want to ask him about the things which would arise during examination of other witnesses and people concerned.

Recently, it has also recorded the statements of several journalists in this regard with whom Sunanda had spoken a day before her death to find out whether she had mentioned to them about the IPL controversy, her husband Tharoor's alleged relations with Pakistani journalist Mehr Tarar or about any plans of hers to hold a press conference.
Journalist Nalini Singh had on Friday told the SIT that she had spoken to Sunanda about taking the blame for her husband in the IPL controversy following which police decided to rope in the Economic Offences Wing (EOW) to examine the business model of the erstwhile IPL Kochi franchise and to understand the controversy surrounding it.
The investigators are now examining whether the IPL controversy had anything to do with Sunanda's death.
The IPL controversy had broken out in early 2010 when Tharoor was Minister of State for External Affairs. There were allegations that he had "misused" his office to ensure that Rs 70 crore, which was equivalent to 19 per cent equity in IPL Kochi franchise Rendezvous Sports, was paid to Sunanda.
Sunanda, who was then a friend and yet to become Tharoor's wife, had refuted allegations of any wrongdoing. She had also denied that she was acting as the front for Tharoor in the Kochi IPL franchise.
Later, she quit Rendezvous Sports World after deciding to return her free equity worth Rs 70 crore to the franchise.
