Bassi also said that the former Union Minister was "cooperative" during the questioning while maintaining that their objective was to reach to the bottom of the truth for which they will look into everything "relevant" to the case, including the IPL angle.
Police sources said other than various matters that could be related to the incident, 58-year-old Tharoor was also questioned about the IPL controversy.
They said that the police may call the Congress MP for questioning again in the next couple of days even as Bassi noted that some more people will be called as the process of investigation is on.
Asked about the further course of action of the Special Investigation Team in the case, he said that the SIT will analyse what Tharoor had told them and then take further action.
