Out of a crowd of 60,000,
Mr "Ao", who is accused of "economic crimes", was found and arrested by Chinese officials using facial recognition technology. Mr Ao was attending a concert by pop star Jacky Cheung. Mr Ao was identified by cameras at the concert's ticket entrance, and apprehended by police after he had sat down with other concert goers. This is not the first time Chinese police have used facial recognition systems to catch suspects. In August last year, police in Shandong province arrested 25 suspects using a facial recognition system that was set up at the Qingdao International Beer Festival.
