Patong Police were informed of the incident at about 7:30pm, and officers soon arrived at the scene.
About 10 people in total were involved in the incident. One man was rushed to Patong Hospital with a serious head injury, Patong Police noted in their report.
Both groups involved in the brawl worked for the same employer. However, there had been ongoing arguments over injuries at work.
The two groups were both travelling towards the roundabout in separate vehicles, shouting at each other. By the time they reached the roundabout, tempers had boiled over and one vehicle collided with the other.
At that point, members of both groups exited their vehicles and the brawl ensued, with some of the workers using weapons to physically attack each other, police said.
In one video of the incident posted online, a man can be seen walking away from the brawl carrying a tyre iron.
All 10 were taken to Patong Police Station where they were to face legal action, Patong Police reported.
No names of those charged were reported by police, and the specific charges levied by police were also not mentioned in the police report.
