On Tuesday, the Centre handed over the probe to the CBI on the recommendation of the Uttar Pradesh government. The state government has come under severe criticism for failing to provide security to the 19-year-old woman who was allegedly raped by the BJP MLA in 2017 when she was a minor.
The FIR filed by the CBI had booked Sengar and nine other associates for alleged criminal conspiracy, murder, attempt to murder and criminal intimidation.
The letter narrates the incidents of July 7-8 when some people allegedly associated with Sengar, the sitting BJP legislator, threatened the victim's family with dire consequences.
The team will go into all the aspects and probe the incident till the CBI takes over the probe, the officer said.
The development comes a day after senior politicians from different opposition parties demanded a free and fair probe into the accident of the Unnao rape survivor and her family.

The FIR, in which 15-20 unnamed people were also mentioned, was registered at the Gurubuxganj police station in Rae Bareli.
The Congress general secretary was joined by leaders like Ahmed Patel, A K Antony, Ghulam Nabi Azad and Randeep Singh Surjewala, besides hundreds of party workers at the India Gate on Monday in a show of solidarity with the students from Jamia Millia Islamia and several other universities across the country protesting the contentious amended citizenship law.
