The girl, Miss Mo, met the ringleaders of the gang, Mr. Zhang and Mr. Liu, 17, on Tencent’s WeChat service. The service is notoriously popular with people wanting to hook up.

On January 24 at around 9 p.m. Miss Mo met with Mr. Zhang in person for only the second time near Anpu Culture Square. Along with Mr. Liu, Mr. Zhang took her on his motorbike to a reservoir in Anzhai Village.

Upon arriving there, an estimated nine men gang raped Miss Mo, according to the local Public Security Bureau.

After being taken back to Anpu at around 1 a.m. on January 25, Miss Mo went to an internet bar where she told a friend about the incident. The friend then told her father who encouraged her to go to the police.

Seven arrests have been made but Mr. Zhang and one more suspect are still on the run. Mr. Liu, 17, and Mr. Yan, 15, are minors so, if convicted, will receive a lighter sentence than others such as the 28 year-old Mr. Wen.

And let this serve as a reminder:  be careful about who you meet from WeChat.
