The 53-year-old Minister of State for Dairy and Khadi sent his resignation to the Chief Minister's Office.
"I have resigned on moral grounds so that an impartial probe can be carried out as I am not guilty in the alleged case", Nagar told reporters at his residence.
"I sent my hand written resignation to the CMO through a person this morning. After many thoughts and second thoughts, I decided to resign...No one asked me to do this", he said.
When contacted, Press Advisor in CMO Mohd Yasin told PTI that the Chief Minister was in Barmer for a function and he had no information of Nagar's resignation.
After registering the case under various sections of the IPC, police referred the case to CB-CID as it involved an MLA of the present Assembly.
The state's CID-Crime Branch had yesterday begun probing the charges of rape and assault levelled against Nagar.
The woman's statement was recorded and her clothes, which she wore on the day of the alleged crime, were recovered and sent for forensic examination.
"I said earlier also during the Asaram case that no one is above law," he had said.
Media frequently alleges that the government interferes in CBI investigation and that it influenced the recent Asaram case, but the state government never gets involved in any case, Gehlot said.
