Debts and tempers rose fast at an Oddar Meanchey casino where two visitors were arrested for assaulting a local punter on Monday.
Crossing over from Thailand, the two loaned cash to their new friend.
But when they demanded repayment after a losing streak he refused, giving them some sarcasm instead. A fight began, then the suspects fled.
They returned two days later to play more, and were arrested by district police for the attack.
