The Unnao rape survivor, a minor, was allegedly kidnapped and raped by Sengar between June 11-20, 2017. She was then sold for ₹60,000, after which she was recovered at the Maakhi police station.
The survivor was thereafter continuously threatened and warned by the police officials against speaking, as instructed by Sengar.
An FIR finally came to be recorded against Sengar under Sections 363 (punishment for kidnapping), 366 (kidnapping, abducting or inducing woman to compel her marriage, etc), 376 (rape), 506 (punishment for criminal intimidation) of the Indian Penal Code and Sections 3/4 of the POCSO Act in April 2018. Sengar was also arrested pursuant to an order passed by the Allahabad High Court.
The case took a controversial turn after a lorry without a number plate rammed into the car in which the victim was travelling. The victim and her lawyer were critically injured, while two of her aunts passed away. In August 2019, the Supreme Court transferred the trial in four cases relating to the Unnao rape case to Delhi and ordered that the same be held on a day-to-day basis and completed within 45 days.
In December 2021, a Delhi Court had discharged Sengar from this case after finding no prima facie evidence that he orchestrated the accident.
