Chinese police are sporting high-tech sunglasses that can spot suspects in a crowded train station, the newest use of facial recognition technology that has drawn concerns among human rights groups.

In a scene reminiscent of the dystopian sci-fi television show “Black Mirror”, officers in the central city of Zhengzhou are wearing the digital shades amid the crush of travellers heading home during Chinese New Year, the busiest time for the country’s transit system.

So far, the technology has allowed police to nab seven suspects accused of crimes ranging from human trafficking to hit and runs, as well as another 26 people who were using fake IDs, according to the state-owned People’s Daily, quoting the city’s police department.

And:

The glasses have a camera connected to a smartphone-like device that allows the officers to take mugshots of suspicious individuals and compare them to a database back at headquarters.
