The sister of the alleged UP rape victim has lashed out at the authorities saying, "My father has already died and now they say action will be taken." 
"I just want that FIR be written against Arun Singh and Kuldeep Singh and they be arrested. I want justice," she added.

The finger of accusation has so far been pointed at a politician from Adityanath's BJP party — Kuldeep Singh Sengar, the BJP MLA from Unnao. 
The rape victim and her family had on Sunday attempted suicide outside Adityanath's residence, which is when the story hit the national headlines. 
The woman and her family had alleged then that she was raped by the BJP MLA and his fellow accomplices, and that no action had been taken so far.
She added that she and her family were threatened after they filed an FIR, which the police registered after stalling for a year.
The family further alleged that Sengar's brother had thrashed the victim's father on April 3 for refusing to cancel the FIR, but that the police booked the father and locked him up. 
The father died Monday morning, in police custody.

Sengar has so far denied the allegations and called it a conspiracy hatched by his political opponents. 
On Monday, he said he would not resign:
