"We already have a watertight case against the accused and this will add further to the severity of the charges against the perpetrators of the brutal crime," said an officer, adding that it brought the case closer to the definition of "rarest of the rare". The charges against the men initially included common intention, attempt to murder, dacoity and gangrape.
Sources said a meeting with its specially appointed public prosecutors to discuss the issue had been convened on Sunday meeting with several senior police officers in attendance.
Although sources declined to comment on the length of the chargesheet -- a figured deemed "irrelevant to the criminal sections and subsections" -- they said it would be complete by January 1.
"We will ensure that the chargesheet would be clear on the charge of 'common intention' as not even one of the six made the slightest effort to prevent or reduce the intensity of the abuse and torture," said the officer, hinting that a line to this effect would form a part of the chargesheet.
