Bharatiya Janata Party MLA Kuldeep Senger, who is accused of raping a 17-year-old girl in Unnao district, was on Saturday remanded to CBI custody for seven days.
The central investigation agency also arrested Senger's aide Shashi Singh, the woman who reportedly "lured" the victim to the MLA on the pretext of getting her a job.
The probe agency, which had arrested Senger after the order of the Allahabad High Court on Friday, produced him in a special CBI court here around afternoon and sought a remand for 14 days. The court, however, granted a remand for seven days.
The victim had alleged that the lawmaker, his brother and some of their supporters gang-raped her when she had approached Senger for a job.
The victim had attempted self-immolation near Chief Minister Yogi Adityanath's official residence on Sunday in protest against the failure of the police to act against the four-time MLA from Bangarmau but was prevented by some alert cops.
Six police personnel, including the Makhi Station House Officer, has been suspended on charges of laxity. The opposition parties have demanded the resignation of Adityanath on moral grounds.
