Sacked Aam Aadmi Party (AAP) Delhi minister Sandeep Kumar has been sent to 14 days' judicial custody by Delhi's Tis Hazari Court.
Kumar was produced before the court in connection with the sex CD row.
He was arrested on Saturday night, hours after one of the women in the video alleged that he had drugged and raped her a year ago.
The arrest came three days after Kumar was sacked from the Delhi Cabinet following the release of a video showing the complainant and him in a "compromising position".
Kumar also lost his primary party membership. To determine the authenticity of the CD, the Delhi Police's Crime Branch has initiated an investigation.
Kumar was sacked by Chief Minister Arvind Kejriwal after a CD that contained an 'objectionable' video landed at AAP's office in Delhi.
