New Delhi: Congress MP Shashi Tharoor may be questioned soon by the Delhi police in connection with his wife Sunanda Pushkar's death a year ago.
Mr Tharoor arrived in Delhi on Sunday after spending a few days at an ayurvedic resort in Thrissur, Kerala. "I have already spoken with the media (in Kerala)," he said, refusing to respond to questions.
Policemen have been posted outside his home in Lodhi Estate in central Delhi.
Sunanda Pushkar, 52, was found dead in her room at a luxury hotel in Delhi on January 17 last year, days after a public spat on social media with a Pakistani journalist she alleged had an affair with her husband.
Last week, the police filed a murder case and alleged that Ms Pushkar was poisoned - either orally or by injection.
On Saturday, the police said they will question Mr Tharoor but they are yet to decide when. Sources say opinion is divided on whether he should be questioned immediately or after all other witnesses in the case are questioned.
Seven witnesses and close friends of the Tharoors have been questioned in the past week. His domestic helper Narain Singh was also interrogated more than once.
It was revealed recently that Mr Tharoor had, in a letter to the Delhi police in November, alleged that his domestic helper had been beaten and pressured into confessing that Ms Pushkar had been killed jointly by the parliamentarian and him.
In a statement accessed by NDTV, Narain Singh said the Tharoors fought bitterly in the last 12 months of their four-year marriage. He said hours before Ms Pushkar was found dead in her bed at the hotel suite, she had asked for a white outfit to be delivered to her so she could wear it at a press conference that day.
Sources say a medical report highlights that there were several injury marks on Ms Pushkar's body, including a bite mark on her hand. The report, sources say, also mentions shards of glass found on the floor, suggesting a possible scuffle.
