Delhi Police Commissioner B.S. Bassi on Monday said that former union minister Shashi Tharoor will be questioned soon with regard to his wife Sunanda Pushkar's murder probe.
"Shashi Tharoor will be questioned soon. He is out today, but might return by 7 p.m. So maybe, we will talk to him today or tomorrow," said Bassi.
"Whoever might know about the case will be questioned," he added.
The Delhi Police had last week issued a legal notice to Tharoor, asking him to join the murder probe of his wife at the earliest.
Pushkar, who married Tharoor in 2010, had checked into The Leela Hotel in Chanakyapuri a day before her death on January 17, 2014.
Tharoor's aides said the couple had checked into the luxury hotel because of renovation work at his New Delhi bungalow.
Prior to her death, Sunanda was embroiled in a spat with Pakistan-based journalist, Mehr Tarar, whom she accused of stalking her husband.
