China might have some of the most advance technologies in facial recognition, but this man's fate was determined by his dinner.
As reported by the South China Morning Post, the unbelievable arrest came months after Jiangsu province police had been on the hunt for a man by the name Guo Bing, who was suspected of gang crimes, fraud, and extortion.
China’s use of facial recognition technology has been integral in aiding authorities to find suspects on the run. Indeed, according to China Daily, China’s facial recognition technology is now so accurate that it can positively identify 98.1 percent of human faces within 0.8 seconds.
But in the case of Guo, things weren’t that simple. While police were able to locate the building in which Guo had been hiding, they couldn’t narrow down which exact unit he occupied. The building’s high number of tenants also made it more difficult to determine his location, according to Detective Ge Lei.
Upon installing a 24-hour surveillance camera, the police still failed to determine the unit he was in. Instead, they were left with a clue:
“We saw him buying vegetables and hotpot soup base at a market one afternoon,” Ge said, “so we guessed he was going to have hotpot that day.” It was an unorthodox way to track down a suspect but authorities were left with no other option.
With the smell of hotpot in mind, the police started the search and found Guo at the seventh floor of the building.
