Police are reviewing video footage of the bloody clash between football fans at Supachalasai Stadium so it can bring the hooligans to justice.
Many spectators were hurt in the melee and five of them have already lodged complaints with police.
"The victims have received minor injuries," Colonel Paisan Leusomboon, superintendent of Pathum Wan Police Station, said yesterday.
Four of the victims who came forward had supported Muang Thong United, while the other one counted Thai Port as his favourite team.
Paisan said the police investigation would focus on the agitators who started the attacks on others.
"We will ask the court to approve arrest warrants," he said.
A conviction would bring two years in jail and/or Bt4,000 fine.
Paisan vowed to proceed with the case quickly since so many people had their feelings let down.
"This is a traditional match and it's the competition for the King's Trophy," he said. "Football fans should demonstrate sportsmanship."
The Sports Authority of Thailand could also file a complaint because some property at its stadium was damaged, he added.
