Bentong police chief Zaiham Mohd Kahar said police received information about the clash involving about 10 men, aged between 23 and 50, at about 4am.

“Investigations showed that the fight had started due to a misunderstanding between both groups inside the casino,” he said.

All four suspects were sent to hospital for treatment of injuries they suffered in the fight. They will be remanded in custody for two days to assist in investigations.

Zaiham said police were still tracking down the remainder of the gang members involved in the fight after viewing footage of the incident from CCTV recordings.
