"Nagar was called to the Police Headquarters (PHQ) by the CID crime branch for interrogation and recording of voice sample in the alleged rape and assault case," a police spokesman told PTI over phone.
Nagar was being interrogated at PHQ by a team led by crime branch additional SP V K Gaur till late in the evening.
However, when asked about the possibilities of the MLA's arrest, the spokesman said that he was not aware of the developments in this regard.
Nagar, former Minister of State for Dairy and Khadi, resigned on September 19 after he was accused of raping the woman at his residence here.
The former minister denied the charge claiming that his political adversaries had hatched a conspiracy to tarnish his image.
