NEW DELHI: Delhi Police chief B.S. Bassi Tuesday said that if necessary, Congress MP Shashi Tharoor would be questioned again for the mysterious murder of his wife Sunanda Pushkar in January last year.
"We have examined several people related to this case. Some of them are still to be questioned and we are in the process of completing our questioning," Bassi told the media.
Asked about Tharoor's questioning Monday night, he said: "Tharoor was questioned for around three-and-a-half hours...and if necessary he will be called for a second round of questioning."
Police officials refused to share Tharoor's answers during the questioning Monday evening, saying any revelation would hamper the imvestigations.

Tharoor was questioned at the Anti Auto Theft Squad office in south Delhi's Vasant Vihar police station where he reached around 8 p.m. He was questioned till midnight.
Police sources said that the former union minister was "relaxed" while answering the questions and spoke mostly in English.
A five-member team of SIT -- including a deputy commissioner of police, an additional deputy commissioner, an assistant commissioner and two inspectors -- questioned Tharoor for over four hours.
Tharoor was called for questioning for the first time in connection with his wife's murder case.
He reached the national capital Monday from Bengaluru, where he had gone to attend a school function.
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's Leela Palace hotel when Pushkar was found dead.
