The teenager is on the ventilator after the car crash on Sunday, when the Swift Dzire she was travelling in was hit by a truck with its number plate painted black. A First Information Report (FIR) lodged a day after the car crash named Kuldeep Sengar, his brother Manoj Singh Sengar and eight others. The case was subsequently transferred to the CBI.

The girl's family has accused Kuldeep Sengar, the four-time lawmaker charged with her rape, of plotting to kill her to try and escape the law.

The ruling BJP, sharply criticized for delaying action against the lawmaker, expelled him on Thursday. A year ago, the party had suspended him when he was arrested and jailed.

The Supreme Court said the CBI's probe into the car crash must be completed in seven days and the trial all five cases, including the rape case, must end within 45 days. More time could be given for the crash investigation if required, the court said.

The teen and her family had written to the Chief Justice alleging grave danger to their lives and threats from the politician and his aides. The court on Thursday said the teenager, her family and her lawyer must be given immediate protection by the Central Reserve Police Force (CRPF).

The Chief Justice had sought a report from the top court registry on the delay in bringing the July 12 letter to his notice.

The teen's letter reportedly related several incidents between July 7 and 8, when some people allegedly associated with Sengar threatened the survivor's family. The letter also requested the court to ask the police to file a case against the people who allegedly tried to intimidate them.

The letter added to growing evidence of delay in investigations and neglect in BJP-ruled Uttar Pradesh, which has earlier faced allegations of going soft on Sengar.

The girl had said that she was sexually assaulted by the politician when she went to his home for a job in 2017.
