CCTV footage that recently surfaced online shows a large group of men walking into a karaoke lounge and attacking female employees.
According to a Beijing Cream article, the incident took place in Xuzhou, Jiangsu province on Apr 1 after 10pm, though a video was released only days ago.
It is not known what the dispute was about, but a description of the original video says the attack was unprovoked.
One person was sent to a psychiatric hospital and three others were injured following the assault.
