Based on the footage shared of the debacle, it's hard to make out what went down exactly. However, one witness' account detailed that there were two concertgoers who instigated the brawl. One of the instigators ran off after things got heated, but another was grabbed by a security guard. Once Polo G saw the opportunity to get back at this guy who disrupted his show, he starts swinging at him. The videos from the event are chaotic but you can seen bodies flying and Polo G can be made out at moments due to his red t-shirt.
The brawl must have gotten pretty ugly because people were also filmed running for their lives outside the venue and shouting "MOVE!" Toosii, an artist who opened the show, referenced the fight on Twitter on Sunday morning, writing, "Polo swing I swing." Polo G has not commented on the altercation.
