A British man and his wife went on trial in Shanghai today for illegally obtaining and selling private information about Chinese nationals.
The arrest of Peter William Humphrey and Yingzeng Yu last year coincided with a Chinese bribery investigation into pharmaceutical company GlaxoSmithKline.
The couple were investigators who operated a small firm in China that helped corporate clients screen potential partners and employees and watch for embezzlement.
Glaxo said it hired Yu and Humphrey to investigate a security breach but prosecutors have not said whether the two cases are linked.
