Friendly game ends not so friendly

Sakon Nakhon Hosted Nakhon Phanom in a friendly game yesterday afternoon. With approximately 10 to 15 minutes left to play a fistfight broke out.  From the way I saw it a Nakhon Phanom player threw the first punch.   Referees quickly separated the combatants and decided to end the game  The Game ended tied at 1-1
