Towards the end of the film, when the team is in search of the missing girl, they cross a swamp. When they come out on the other side, their clothes are clean and dry.
When Ayan Ranjan (Ayushmann Khurrana) interrogates Nihal Singh (Sushil Pandey) by the side of the highway after learning of his involvement in the crime, Nihal Singh's gun strap switches between his left and right shoulders between shots. This continues until he hands off the gun.
The police were calling Ayushman as ADDL Commissioner,but insignia on his shoulder were of SP which is superintendent of police .The insignia for Addl is three star and National emblem.
Actually it is incorrectly mentioned. The insignia of Additional SP Is not The Ashoka Emblem and Three star but only The Ashoka Emblem.
