Mumbai: Priyanka Singh and Mitu Singh, sisters of late actor Sushant Singh Rajput, said that Rhea Chakraborty has put forth a “moonshine defence and self-serving averments” in her reply to their petition to quash the first information report (FIR) filed against them over alleged fake prescription for Sushant via telemedicine.

The sisters, in their rejoinder to a reply filed by Rhea, have now sought orders for a probe into her “malicious activities” and “grant damages under public law remedy for malicious prosecution”.

Priyanka (38) and Mitu (45) have petitioned the Bombay High Court to quash the FIR lodged at Bandra police station on information given by Rhea, claiming that the case against them was based on a “concocted story” and “unfounded allegations, unsubstantiated facts, speculations and a misleading complaint”. The “counterblast” FIR makes no case against them and deserves to be quashed, said their rejoinder filed through their advocate Madhav Thorat.

The sisters said Rhea “deliberately concealed” a September 14 letter she had written to police in which she “conceaded that an FIR cannot be registered under IPC Section 306 (abetment of suicide)”.

Bandra police on September 7 registered the FIR that accused the sisters and Delhi-based Dr Tarun Kumar of “alleged offences of conspiracy, cheating and forgery…for fabricating medical prescription” for the late actor’s “anxiety’’ on June 8, without his actual examination.

Mumbai Police, in its affidavit submitted to the high court, had said, “The FIR also seeks investigation into possibility of deterioration of his mental health and eventual suicide pursuant to the conspiracy.” It is now for the CBI to investigate both the FIRs, Mumbai Police had said.

The sisters also claimed that there is no allegation in Rhea’s reply that any such alleged drug was actually administered to Sushant. The drugs prescribed are not banned, but an April 2020 notification and telepsychiatry clearly permits prescription through telemedicine.
