Five men who were allegedly in the car have been booked for culpable homicide among other charges. All five accused were sent to a three-day police custody on Monday.
The friend had earlier claimed that no music was playing in the car that hit both the women and the driver was aware that the victim was being dragged under the wheels but kept moving back and forth despite her cries.
Recalling the fateful night, Anjali Singh's friend had said they had gone to meet some friends at a hotel on New Year and alleged that despite being 'drunk', the victim wanted to ride the scooter after the party.
Delhi Commission For Women (DCW) chief Swati Maliwal cautioned against victim shaming and demanded a probe into the friend's claims.
With the emergence of the eyewitness, police said that her account will be important evidence in getting the accused punished and more CCTV footage has been recovered that could help establish the sequence of events on Sunday night.
