The CBI on Saturday questioned expelled BJP MLA and rape accused Kuldeep Singh Sengar in Sitapur jail in connection with the accident in which the rape survivor was critically injured along with her lawyer and her two aunts were killed, as the agency deputed several teams to speed up the probe.

The three-member CBI team grilled Sengar for several hours in Sitapur district jail, according to officials, days after the Supreme Court asked the agency not to take more than a fortnight to complete the investigation.

The 19-year-old rape survivor, who is on ventilator support, remains critical as she has developed pneumonia, doctors attending to her at a hospital here said. Her lawyer has been taken off the ventilator, but he is still not out of danger.

A CBI team visited the rape survivor's uncle, lodged in a Rae Bareli prison, on Friday. Later in the night, the Rae Bareli administration, in compliance with a Supreme Court directive, shifted the rape survivor's uncle to the Tihar jail in Delhi.

Another four-member CBI team visited the village of the rape survivor in Unnao on Saturday.

According to the police station in-charge, Naradmuni, the team was in the village for hours and returned to Lucknow after conducting investigations. No one from the survivor's family was present in the village at the time of the CBI team's visit, he said.

In Rae Bareli, a CBI team was busy probing the accident by recreating the sequence of events of the accident and also questioned the driver and the cleaner of the truck that had rammed into the car in which the victim was travelling with her family members and lawyer.
