The CBI will investigate three cases filed against Sengar in Unnao, 50 kilometres from state capital Lucknow.
The BJP MLA has been charged under the stringent POCSO Act and sections of the Indian Penal Code or IPC dealing with rape.
The notice to the CBI to take over the Unnao case was issued on Thursday night, following which the probe agency in a matter of a few hours picked up the BJP legislator from his Lucknow home at 4:30 am.Yesterday, the Allahabad High Court had come down heavily on the UP government, asking it whether it proposes to arrest Sengar over the Unnao rape case.A bench of Chief Justice DB Bhosale and Justice Suneet Kumar, taking cognisance of the Unnao gang-rape case on a letter to the court by senior lawyer Gopal Swaroop Chaturvedi, heard the matter in detail. It will pronounce its order today.
The court also questioned the conduct of the police in the case.
The teen from Unnao has accused the legislator of raping her in June last year. Advocate General Raghavendra Singh, who was present in the court on Thursday, told the bench that on August 17, 2017, an application was sent to the Chief Minister Yogi Adityanath's office in which allegations of rape was made against the lawmaker.
On Wednesday night, Sengar made a dramatic appearance outside the house of the police chief in Lucknow, in a convoy of 20 vehicles. "I have come here because TV channels were saying I will surrender," he appeared to taunt reporters, insisting that he was neither a fugitive nor a rapist.
