"It is Dayan Krishnan, an eminent lawyer... He has volunteered to do it free of cost. He will be assisted by two juniors," Dharmendra Kumar, Special Commissioner of Police (Law and Order), told PTI.
The senior police officer said the harshest punishment would be sought against five accused during the trial after filing the charge sheet by Jan 3. The sixth accused is a juvenile and would be tried separately at Juvenile Justice Board.
"We hope to file the charge sheet by Jan 3, 2013. Section 302 of the IPC, which is the penal section for murder, has been added in the FIR," Kumar said, adding, "It will be our endeavor to ensure the harshest punishment in the book for the culprits."
The special prosecutor would conduct the trial in a fast track court on day-to-day basis.
Later talking to PTI, Krishnan said, "I had given my consent to conduct the trial. Till now, I have not received any notification."
Krishnan has been representing NIA, Delhi Police and other agencies at various judicial fora in many cases including the Nitish Katara murder case.
