He said that Indians all over are watching "keenly".

"After Kangana Team's tweet to PMO India, Justice for SSR and Clean Bollywood are now getting into one big-movement Swachha Bollywood...Swachha Bharat...," he said in a series of tweets.
The Narcotics Control Bureau (NCB) has registered a case against Ms Chakraborty and others in connection with Sushant Rajput's death case.
The NCB has registered the case under various sections of the Narcotic Drugs and Psychotropic Substances (NDPS) Act, 1985, including Section 27 which specifies punishment for consumption of any narcotic drug or psychotropic substance and 29 which provides for punishment in case of abetment and criminal conspiracy.
The ED had on July 31 registered an Enforcement Case Information Report (ECIR) in the late actor's death case after a First Information Report (FIR) was filed by Sushant Rajput's father KK Singh against actor Rhea Chakraborty in Bihar on July 28.
On August 19, the Supreme Court had asked the probe agency to investigate the case related to the actor's death, while holding that the FIR registered in Patna was legitimate.
The agency has registered an FIR against Chakraborty and others in connection with the actor's death after the Centre accepted Bihar government's recommendation to transfer the probe in the matter from Patna.
Sushant Rajput was found dead at his residence on June 14.
