New Delhi, Jan 19 (IANS): Delhi Police Monday issued notice to Congress MP Shashi Tharoor to join the investigation into his wife Sunanda Pushkar's murder, and he will be questioned within two days, police chief B.S Bassi said.

"We have issued notice to Tharoor. He will be questioned tomorrow (Tuesday) or day after (Wednesday)," Bassi told the media.

The police commissioner said the Special Investigation Team (SIT) has already questioned many people found to be connected with the case, and a few more remain.

"He (Tharoor) has not been questioned. I would like to tell you that everybody who has information in this case, we will talk to them and look at specifics which throw light," Bassi said.

Tharoor, meanwhile, reached the national capital Monday from Bengaluru, where he had gone to attend a school function.

He reached the Indira Gandhi International (IGI) airport around 2 p.m. He directly went to his house in Lodhi Estate area in central Delhi without answering questions from the media standing outside the airport.

The SIT has questioned at least 12 people, including Tharoor's security staff members and domestic help, who were present in the hotel in south Delhi where Pushkar was found murdered Jan 17, 2014.

On reports about then information and broadcasting minister Manish Tewari being present in the flight from Kerala Jan 15 on which the couple had a fight, Bassi said "the possibility cannot be ruled out".

Bassi said the process of sending the viscera of Pushkar to the US for special investigation was on.

Pushkar was found dead in a hotel room Jan 17, 2014. Police registered a case of murder early this year soon after getting the final autopsy report from the All India Institute of Medical Sciences (AIIMS).
