Investigators jailed in China

A British man and his American wife have been handed prison terms on charges of illegally trading in the personal details of Chinese citizens after they testified that they bought such information to help companies combat fraud.

Peter Humphrey and Yingzeng Yu operated a firm in Shanghai that helped companies screen potential business partners and employees. Their arrest last August sent a chill through foreign businesses, and came as Beijing tightened controls over information and prompted warnings that investigation of legitimate matters might be curtailed.
