Delhi Police Monday began questioning Congress MP Shashi Tharoor in the mysterious murder of his wife Sunanda Pushkar in January last year.
Tharoor reached the Vasant Vihar police station in south Delhi Monday evening - a few hours after he was issued a notice.
Police had constituted a special investigative team (SIT) to probe the murder after registering a FIR in the case Jan 1 this year. The FIR was filed based on Pushkar's third autopsy report by the AIIMS medical board.
