The crime branch, probing the case, is also planning to record a supplementary statement of the victim, a 23-year-old photojournalist working as an intern with an English magazine, Joint Commissioner (crime) Himanshu Roy said.
"To build a foolproof case, reconstruction of sequence of events that led to the crime was done today. We want to make a watertight case so that no room is left for the defence to find loopholes in the probe," Roy, who accompanied the five accused to the scene of the crime, told reporters.
The accused were made to enact the entire sequence of events--from the point they directed the unsuspecting victim and her male colleague to a pathway to the defunct and deserted compound to the commission of rape.
"The accused were taken to the spot where they demonstrated how the crime was perpetrated. We got more clarity and better understanding of what happened. We are confident of building a strong case and determined to bring it to the logical end," he said, adding the entire proceeding, lasting about an-hour-and-half, was videographed.
Roy said an 'Odhani' (stole), which did not belong to the victim, was recovered from the spot and DNA samples would be picked up from it to be matched with those of the accused. The perpetrators had wiped themselves with the stole after committing rape.
The police had yesterday seized clothes, including undergarments, worn by the suspects at the time of the incident during searches at their homes.
Asked about the reason why a supplementary statement of the victim needed to be recorded, Roy said since she was traumatised immediately after the incident, she might have omitted some points inadvertently.
Meanwhile, the young journalist has been discharged from hospital after doctors attending on her declared her "medically fit".
"The patient had improved steadily and our team of doctors specially assigned, had declared the patient medically fit for discharge last evening and hence she was discharged late last night," a statement from Jaslok Hospital said.
"Best quality medical care was given to the patient at all times at the hospital," the statement issued by Dr Tarang Gianchandani, acting CEO and Director, Medical Services, said.
