Congress MP Shashi Tharoor Sunday reached the national capital and is likely to be questioned by Delhi Police in connection with his wife Sunanda Pushkar's murder.
Tharoor arrived at the Indira Gandhi International (IGI) airport from Kerala around 2 p.m. and went to his house in central Delhi's Lodhi Estate.
Tharoor did not reply to questions from journalists, and merely said: "I have already spoken with the media (in Kerala)."
He drove away in a car with his security staff.
Policemen have been deployed outside his residence. Tharoor was undergoing ayurvedic rejuvenation in Thrissur district of Kerala.
Pushkar, 52, was found dead in mysterious circumstances in a luxury hotel here Jan 17, 2014.
On Saturday, Delhi Police said they will question Tharoor after the people who were in the hotel and in touch with Pushkar before she was found murdered.
Police have compiled a list of people to be questioned in the case.
