Addressing a press conference, Deshmukh said, "It has been more than five months since the investigation began but CBI has not revealed if actor Sushant Singh Rajput was murdered or he died by suicide. I request CBI to reveal findings of the investigation at the earliest."
"Five to six months have passed since the case was handed over to the CBI. Hence, the agency should make public its report as soon as possible to clear whether it was suicide or murder," Deshmukh added.
Earlier, the Mumbai Police had filed an accidental death report and they were probing the case.
On 19 August, the apex court had upheld the transfer of an FIR, lodged by Rajput's father at Patna against the actor's girlfriend Rhea Chakraborty and others for allegedly abetting his suicide, to the CBI.
The central agency had then taken over the probe from Bihar Police.
In October, the medical board of the New Delhi-based All India Institute of Medical Sciences (AIIMS) had ruled out murder in the death of Rajput, terming it "a case of hanging and death by suicide".
