The Central Bureau of Investigation was on Tuesday handed over the inquiry into a car crash in which the complainant in the Unnao rape case and her lawyer were seriously injured and two of her aunts were killed, PTI reported, quoting a central government order.

The order by the Department of Personnel and Training said the case was being handed over to the CBI to look into “abetment and conspiracies” into the accident, according to PTI.

Earlier in the day, the Uttar Pradesh Police had formed a Special Investigation Team to investigate the accident, which took place in Rae Bareli district on Sunday. The complainant’s family has alleged that Kuldeep Singh Sengar, the Bharatiya Janata Party MLA accused of rape, was behind the incident. The CBI is looking into the rape case as well.

The state government had on Monday night recommended a CBI inquiry into the car crash after the complainant’s uncle made a request.

On Monday, the state police booked Sengar, his brother Manoj Singh Sengar and eight others on murder charges in connection with the car crash. Sengar is lodged in Sitapur district jail at present. According to the first information report, the personnel in charge of the complainant’s security had informed him of her movements.

Director General of Police OP Singh said on Monday that preliminary inquiries suggested it was an accident caused by a speeding truck and there was no negligence in the security provided to the complainant. “Due to lack of space in her vehicle, she requested the security personnel deputed for security not to accompany her to Rae Bareli yesterday,” he had said. Unnao Superintendent of Police Madhav Prasad Verma also confirmed that the security officer who usually accompanies the family was not with them on Sunday.
