The 13-year-old girl, whose family lives on a pavement, was alleged to have been dragged inside the cab and raped on Sunday night in the Rafi Ahmed Kidwai Road - close to Park Street.
One person has been arrested in connection with the incident, while a manhunt was on to nab the taxi driver and an accomplice.
In February 2012, an Anglo-Indian woman was allegedly raped by a group of youths who befriended her in a night club in the area.
The sensational crime shocked the city, and the case continues to be heard in court. But the prime suspect is still at large.
