In a communication, the Home Ministry asked the state government to provide details of the incident and steps taken to nab all those involved in it, official sources said.
The Uttar Pradesh government has been told to send the report as early as possible, sources said.
A gang of dacoits had brutally raped a woman and her 13-year-old daughter at gunpoint after dragging them out of a car in Bulandshahr on NH-91 when they were travelling with their family from Noida to Shahjahanpur on Friday night.
Facing flak from opposition, the state government had suspended five officers, including district SSP Vaibhav Krishna.
