China's Tencent says former executive, others implicated in corruption case

Tencent Inc., operator of the popular WeChat social media service and China's most valuable tech company, says the former general manager of its video unit and other employees are implicated in a criminal corruption case.

Tencent said Friday an audit last year raised doubts about the acquisition process for its video content. The company said it notified police, who have detained five or six employees. It gave no other details.

The company identified the executive as Liu Chunning, also known as Patrick Liu. A rival company, Alibaba Group, where Liu went to work after leaving Tencent, said Thursday that Liu had been detained in connection with his former work at Tencent.
