A fight broke out at 1 a.m. on the 6th floor of ATT4Fun in Xinyi District. One man involved in the altercation stabbed three others with a belt knife, Apple Daily reported.

The two men and one woman were taken to the hospital and their injuries were reportedly not life threatening. One 22-year-old woman was stabbed in the buttocks. The two men, also 22 years old, were stabbed in the arm and thigh, respectively.

The fight involving seven or eight people, according to police, started with the people allegedly bumping into one another on the dance floor. Witnesses claim that the dance floor was crowded and there was little room to move without pushing others.

Police are reviewing surveillance footage to identify the person responsible for the stabbing.

Update: The incident occurred at ELEKTRO, according to Liberty Times. Police identified a man surnamed Lin (林) as the suspect in the stabbing. He allegedly discarded the knife upon fleeing the scene. According to the report, Lin said that he was offended the other party was too close to a female companion.

This is not the first incident at the clubs at ATT4Fun. In August 2016, one man was killed after a drunken argument led to a stabbing at WAVE nightclub.
