A star student from a China’s top university who is suspected of killing his mother was detained by police at a Chongqing airport on April 20 after being identified by surveillance equipment using facial recognition technology, reported Chinese media on Saturday.

A former economics student at the renowned Peking University, 25-year-old Wu Xieyu had been in hiding for more than three years using a number of fake IDs. At the time of the arrest, Wu was seeing two friends off at the airport. Fewer than 10 minutes after he appeared at the airport, the police approached him, The Paper reported, citing one of Wu’s friends.

The capture comes half a year after the Chongqing airport significantly upgraded its surveillance system to include facial recognition technology provided by artificial intelligence (AI) startup Cloudwalk. According to an announcement released in September, the updated system communicates in real time with a police database, and sends warnings immediately following an identification. A Cloudwalk spokesman declined to comment when contacted by TechNode on Sunday.
