To compare the gait of Assistant Police Inspector Sachin Waze with that of the man spotted in PPE suit outside industrialist Mukesh Ambani`s residence Antilia on the night of February 25, the NIA is likely to conduct forensic podiatry. An expert, while speaking to mid-day, explains how this forensic science works.

Dr Hemlata Pandey, a forensic expert from Mumbai`s KEM hospital, said, “In forensic podiatry, foot or footprints of an individual in a crime scene or CCTV footage is studied to get the walking patterns of criminals. The investigators measure the step as well as stride lengths, and the length of foot and ankle to further match with the walking or gait patterns of the suspect in the footage."
