Pakistani journalist Mehr Tarar is likely to be questioned in connection with the murder of Sunanda Pushkar, wife of Congress MP Shashi Tharoor, police said on Thursday.
"Tarar is a relevant person in the case... If necessary, she will be examined," said Delhi Police Commissioner B.S. Bassi.
Tarar's friendship with Tharoor had reportedly led to a row between Tharoor and Pushkar.
Delhi Police constituted a Special Investigation Team (SIT) after registering a murder case against unknown people on January 1. Pushkar was found dead in a luxury hotel room on January 17, 2014 under mysterious circumstances.
The SIT probing the case has so far questioned at least 15 people, including Tharoor, his staff members, close friends of the couple and the staff of Leela Palace hotel where Pushkar was found dead.
