The former partners who had unresolved issues with each other, verbally abused each other during the first game, being warned by the umpire.
The abuse continued at the end of the game, leading Issara to chase Jongit across the arena.
The two were eventually broken up by Issara's partner and their coach before police and security intervened.
After the fight, the tournament referee showed Issara and Vilailak a black card, meaning they were ejected from the tournament, consequently awarding the championship to Jongjit and Puangpuapech.
Both Issara and Jongjit received sanctions from the Badminton World Federation and from the Badminton Association of Thailand: Issara, who was deemed to be the instigator and more physically abusive, was banned for two years from participating in any international tournaments, while Jongjit, who had provoked Issara during the match, was banned for three months.
