A separate application was also submitted to the investing agency by Nagar for conducting narco-analysis test on him.
“Nagar wanted that a narco-analysis test be conducted on him so we gave a separate application to CBI,” Jain told reporters.
Police had booked Nagar on charges of raping and beating up the woman on September 11, after calling her to his official bungalow here on the pretext of giving her a job.
The CBI on October 9 took over the probe from Rajasthan Police which had registered the case against Nagar, following which he resigned as the Minister of Dairy, Khadi and Rural Industries in the Ashok Gehlot Government.
The former Rajasthan minister has told investigators that he had a sexual relationship with the rape victim for the last three and a half years, and that he was being framed by his political rivals.
Nagar's arrest comes 38 days after the 35-year-old woman filed a sexual assault charge.
