"Since various issues are being raised with respect to the circumstances of this death, it would be absolutely important that a very fair inquiry is held so that all doubts can be put to rest," Union Finance Minister Arun Jaitley said.
In a tweet, the minister also condoled the "sad and untimely" demise of the 38-year-old journalist and said that his "thoughts and prayers are with the bereaved family".
He said, "If we see the scams -- be it the Vyapam scam, the rice scam in Chhattisgarh or what is happening in Rajasthan, with ministers in the Modi government, the Prime Minister seems to be not breaking his silence.
"It seems that he has given tacit support to all these scams. It is extremely evident."
On its demand that MP Chief Minister Shivraj Singh Chouhan should seek a CBI probe, he said, "Why not have a CBI inquiry? What he is saying will be only credible once the CBI gives him a clean chit.
"That definitely means that he has something to hide. How many more deaths will it take for the central and state governments before a fair trial is ordered.
