Around 35,000 people flocked to the MA Chidambaram Stadium — also known as Chepauk — to watch the M S Dhoni versus Virat Kohli duel on March 28. During the match, the Greater Chennai Police received a notification of a stolen mobile phone through the QR code pasted in different parts of the stadium. To pick from the crowded stands was a difficult task. But police not only found the offender but also recovered 84 stolen phones, including those picked from the stadium, in just two days. Behind the mystery-solving was forensic combing powered by the Greater Chennai Police’s AI-driven security platform Chennai Singam, a face recognition software and surveillance cameras, apart from the hundreds of policemen scattered in and around the arena. Their eyes are all-pervasive, watching every step a spectator, or even a dog or cat, takes in the stadium. The colour of their clothes are taken note of. So are the words on the banners and posters as well as those showing any suspicious behaviour, who could potentially be a punter, pickpocket, or a chain-snatcher. Crowd control, obviously, goes on routinely.
