The employee, identified by his surname Wang, was detained by police last month after a female Alibaba employee posted an 11-page account on Alibaba’s intranet saying a manager and a client sexually assaulted her during a business trip to eastern China’s Jinan city.

She said superiors and human resources did not take her report seriously, triggering a fierce public backlash against the e-commerce giant, which later fired Wang and suspended other executives.

Prosecutors have, however, approved the arrest of the client who has been identified by his surname Zhang.

Reuters was unable to reach Wang or Zhang for comment.

Alibaba said in response to the decision by prosecutors that it has a zero-tolerance policy for sexual misconduct.

Alibaba dismissed 10 employees for sharing screenshots of the female colleague’s account of sexual assault allegations, Bloomberg News reported last month, citing people familiar with the matter.
