Alibaba executive detained over Tencent graft

Alibaba Group Holding Ltd was put under the spotlight after police detained Patrick Liu, president of the e-commerce giant's digital entertainment unit.

The company said in a statement on its microblog on Friday that Liu was taken into custody for his alleged involvement in a bribery case while he was working at Tencent Holdings Ltd.

Emphasizing the case has nothing to do with Alibaba, the Hangzhou-based company said: "We have already taken steps to ensure that the detention will not affect the business of Alibaba Pictures Group Ltd."
