A British company investigator, Peter Humphrey, has been sentenced to two-and-a-half years in jail for trafficking personal data in China.
The Shanghai court also sentenced his American wife Yu Yingzeng to two years.
GlaxoSmithKline (GSK) China, which is being investigated for possible bribery, hired Mr Humphrey last year.
The pair were found guilty of illegally obtaining Chinese citizens' data and selling it to China-based multinational firms, including GSK China.
Both admitted buying background information - but said they did not realise it was illegal to do so.
They have the right to appeal against their sentences within 10 days.
A court official also announced that Humphrey would be deported, but gave no further details, Reuters news agency reports.
