Ms. Shipra is a renowned scientist in TIFR, Mumbai. She recently discovered a new way of gaining huge energy from the water-current at a much lower cost. Considering its future application, many companies were after her research paper. She finally decided to file the patent. On February 4th, 2016 she visits the Indian Patent Office in Mumbai. After 3 minutes of submitting the paper, one officer in the office found that the main paper is missing. Everybody, including who were present in the office and who entered and left the office during that period, was body-searched but the paper was not found. Here is the link of the CCTV footage of 3 minutes during which the paper was stolen. (In this video, the first girl entering is Ms. Shipra.)
Can you determine who stole the paper, and why was he/she not caught during searching?
The old man with the walking stick came with the stick in the left hand and after all the mess, he walks out with the stick in his right hand. The question still remains, where did he hide the documents? If we watch carefully, it looks like the guy in the black and white checkered shirt exchanged something with the old man. Is he also involved?
