CJI Ranjan Gogoi has asked the court registry to submit details of the letter.

Over 15 days before a road accident in Uttar Pradesh's Raebareli left the Unnao rape survivor critically injured and killed two of her relatives, she had written a letter to the Chief Justice of India (CJI) claiming that they faced grave danger to their lives.

Now, amid allegations that the accident was orchestrated by Kuldeep Sengar, the BJP lawmaker accused of raping the teenager in 2017, Chief Justice Ranjan Gogoi has directed the court registry to submit details of the letter. "The CJI has asked the Secretary General to go through the letter written in Hindi for preparing a note of it for his perusal," an official of the Supreme Court said.

On Sunday, the teen, her two aunts and her lawyer were travelling from Unnao to Raebareli when a truck with its number plate wiped rammed their car. The driver of the truck and its owner have been arrested.

The investigation into the road accident has now been transferred to the CBI.

The letter reportedly related several incidents that occurred between July 7 and 8, when some people allegedly associated with Kuldeep Sengar, jailed since last April, 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.

Kuldeep Sengar, a four-time BJP lawmaker from Uttar Pradesh's Bangermau, was arrested last April on charges of rape amid allegations that the state government was deliberately soft on him.

Following taunts by opposition leaders including Congress general secretary Priyanka Gandhi Vadra, the Uttar Pradesh BJP on Tuesday claimed that he was suspended from the party in 2018.

A First Information Report (FIR) lodged a day after the car crash named the BJP legislator, his brother Manoj Singh Sengar and eight others as the accused.

The teen alleges that she was sexually assaulted by the lawmaker when she went to his Unnao home to seek a job in 2017.

Months after she went public with the allegation, her father was brutally beaten up by Kuldeep Sengar's brother Atul. The police, instead of providing the rape survivor's father with medical aid, arrested him for allegedly possessing illegal arms. Following this, Atul Sengar was also arrested on charges of murder.
