The application was moved by the youth's mother before a bench of Justice V P Vaish, saying a neutral agency like the Central Vigilance Commission (CVC) should be appointed for carrying out a "fair, unjust and unbiased inquiry" in such a "gruesome crime".
Advocate Prashant Bhushan, appearing for the petitioner, said that during the departmental inquiry proceedings, the three policemen had deposed that there was nothing wrong in their action and tried to justify it.
The court asked Delhi Police Standing Counsel Rahul Mehra to file a status report and posted the matter for October 26.
The woman, in her plea, also alleged that the FIR registered against one of the three cops against whom probe was initiated, created doubt about the fairness of the inquiry initiated by police "which seems nothing more than eyewash."
