Rajasthan minister Maderna accused of rape and murder
The case received attention from the media after Amarchand, the victim's husband threatened self-immolation.
He maintained that the minister's name had been removed from the complaint he had filed.
A month after the case was registered, he claimed that investigations were purposefully moving slowly.
Opposition party BJP is also putting pressure on the minister to resign.
Maderna is the son of prominent Jat community leader Parasram Maderna and represents the Osian constituency of Jodhpur in the state assembly.
