Alibaba Group Holding, China’s biggest e-commerce company, said a former general manager of its group-buying website was detained by the police on suspicion of accepting bribes.

The official of the Juhuasuan website was removed from his position in March for misconduct, according to a statement on Alibaba’s e-commerce website Taobao.com.

Taobao, China’s biggest online shopping website with 500 million user accounts, set up a department in 2010 to handle complaints about the behavior of employees.

In May, Alibaba said police arrested some workers at the Internet shopping site after a “small” number were accused of accepting improper benefits from vendors.

In February 2011, Alibaba.com said an internal probe found more than 2,300 vendors used its website to defraud global buyers.

Yahoo! owns 40 percent of Alibaba.
