During a change of ends, Issara chased Jongjit onto a neighbouring court before tackling him to the ground and viciously punching him several times to leave him needing two stitches.

Issara was pulled off his former teammate and held down by staff as Jongjit was escorted - now shirtless - off court.

The pair had already received a warning from the referee following a verbal altercation earlier in the match.

The unfortunate scuffle saw Jongjit and his partner Nipitphon Puangpuapech awarded the victory after Issara and his teammate Pakkawat Vilailak were disqualified.

"The events surrounding the conclusion of this match will be thoroughly investigated by the BWF," read a statement from the sport's international federation.

"The world-governing body has procedures in place to deal with such situations and this matter will be referred to the Disciplinary Committee."

The statement added that no further comment would be made by the BWF until the process has been concluded.

Issara and Jongjit split in January, when Issara retired because of injury and to look after his ailing mother, but he soon resume professional competition with his new partner.
