Refuting allegations of political pressure in Sunanda Pushkar death probe, Home Minister Rajnath Singh today said Delhi Police is conducting an impartial investigation.
"There is no political pressure. An impartial inquiry is taking place. There is no instruction from our side," he told reporters in New Delhi.
Singh was replying to questions on the probe into the mysterious death of Sunanda, wife of Congress MP Shashi Tharoor, in January 2014.
Tharoor has recently demanded an impartial and speedy investigation without any political pressure on investigators.
The Congress Party has said there was a "sustained misinformation campaign based on insinuation and innuendos" against Tharoor and stressed he was not an accused in the case.
"Whatever the Delhi Police does, they do it in an impartial manner," Singh said today.
In January, Delhi Police registered a case of murder in connection with Sunanda's death under Section 302 of IPC on the basis of an AIIMS medical report that concluded her death was unnatural and due to poisoning. But the report did not reveal the nature and the quantity of the poison.
