Chinese prosecutors have closed a case against a former Alibaba Group Holding Ltd employee who was accused of sexually assaulting a female colleague.

The employee, identified by his last name Wang, was arrested by police last month after an Alibaba employee posted an 11-page account on the Alibaba intranet claiming a manager and customer had them during one Sexually abused business trip to the east China city of Jinan.

She said supervisors and human resources did not take her report seriously, sparking a violent public backlash against the e-commerce giant who later fired Wang and suspended other executives.

An employee posted an 11-page account on the Alibaba intranet in early August alleging that her manager and a customer had sexually abused her, and that managers and HR had not taken the matter seriously in the five days since it was reported.

However, the prosecution approved the arrest of the client, who was identified by his last name, Zhang. Reuters was unable to reach Wang or Zhang for comment.

Alibaba said in response to the prosecutor’s decision that it has a zero tolerance policy for sexual misconduct.

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