Chinese police have used facial recognition technology to locate and arrest a man who was among a crowd of 60,000 concert goers.

The suspect, who has been identified only as Mr Ao, was attending a concert by pop star Jacky Cheung in Nanchang city last weekend when he was caught.

Police said the 31-year-old, who was wanted for “economic crimes”, was “shocked” when he was caught. China has a huge surveillance network of over 170 million CCTV cameras.

The future.
