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."

Liu joined Alibaba in August 2013, a month after he resigned from Tencent where he acted as the head of video department. Liu has been in charge of online literature and Yulebao, the world's first platform for individuals to invest in movies, at Alibaba.

The company said it will provide legal support to Liu who is also an executive director of Alibaba Pictures. Alibaba owns a 60 percent stake in the film studio.

In response to the arrest, Tencent said Liu was one of the five or six former employees who were detained by the police after a graft investigation.

"An internal probe brought to light bribery and corruption among some online video employees. We have already notified the police," the Tencent said.

The scandal comes as Alibaba Pictures ramps up efforts to expand its presence in the movie industry. Last month, the Hong Kong-listed company acquired a major software solution provider in China's film market with $134 million, making Alibaba the first Internet giant, compared with its major rivals Baidu Inc and Tencent, to expand into all movie-related businesses.

Huang Guofeng, an analyst at Beijing-based Internet consultancy Analysys International, said the case will have more impact on Alibaba's reputation than on its business operations.
