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. After reaching home, he consulted his lawyers and discussed the case.

 

 Policemen have been deployed outside his residence.

 

 Tharoor was undergoing ayurvedic rejuvenation in Thrissur district of Kerala. Soon after his discharge, he raised questions on the Delhi Police investigation and demanded a professional probe.

 

 He also said he wrote to Delhi Police Commissioner B.S. Bassi, assuring him full cooperation with the investigating team.

 

 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. They have already questioned Tharoor's domestic help Shri Narain Singh, who told them there was a fight between Tharoor and Pushkar, a day before she was found dead.

 

 In November last year, police also questioned Pushkar's businessman friend Sunil Trakru – who had then dropped Pushkar at the hotel when she came to Delhi in January 2014.

 

 A police official said Pushkar's viscera samples would soon be sent abroad for ascertaining the poisonous substance administered to her.

 

 The case was registered Jan 1, almost a year after her death, following the final post-mortem report from the All India Institute of Medical Sciences (AIIMS) that was submitted Dec 28, last year.

 

 Police had collected pieces of broken glass from Pushkar's hotel room which purportedly implied that a scuffle took place inside the room before her death.
