What is the common link in cracking the Nirbhaya gangrape case, Kailash Satyarthi Nobel Prize citation theft case and the Dhaula Kuan gangrape case?
Apart from they being high-profile cases spread over nearly seven years, they tested the nerve of Delhi Police.
In December 2012, a 23-year-old female physiotherapy intern was gangraped and tortured by six men in a moving bus in a South Delhi neighbourhood. The men later threw her out of the bus onto a road. She succumbed to her injuries on December 29 that year at Mount Elizabeth Hospital in Singapore.
The first clue in cracking the case came from the CCTV camera footage of the bus in which the woman was brutalised.
"The camera had captured a photo of the vehicle and policemen were present at my home for three days. I worked on developing clues from the footage. We found that it had an extra headlight and 'tripals' were kept in it," Singh said, recalling that this helped the investiagtors in concluding that thevehicle was a pick-up van.
Subsequently the accused were arrested and the vehicle, used mostly by people based in Mewat region, was also found.
"The accused had come for a recce during the day, and in the night we had images that were not very clear. But we compared the heights of the men who had visited the area during daytime. Subsequently, police identified the three brothers involved in the case," said one of the students.
"There are times when they give us footage of masked men and and ask us to tell them how the person would look without the mask. At other times, they ask us to remove the helmet of the driver and show them his features," another student said.
The students said they enjoy helping investigators nonetheless. It's fun sometimes, they said.
"We have also seen footage where the accused are seen flying like Superman to break the cameras or turning them towards the other direction," another student added.
