All casinos have a built-in house edge, but in Cambodia that edge can actually draw blood.

On Wednesday, police in the Cambodian city of Sihanoukville arrested two Chinese employees of the Leu Phnom Casino for stabbing and robbing two other Chinese nationals. The Khmer Times quoted the local police chief saying the four men were known to each other prior to the attack.

The two 22-year-old casino staffers reportedly tried their hand at the other side of the gambling table, only to go broke in the process. Short of cash, they decided to rob their countrymen, who were sleeping in the casino’s staff quarters at the time.

Awakened at knifepoint, the two victims resisted, only to be stabbed in the arm and back when they didn’t make with the money fast enough. The staff/thieves relieved their friends/victims of around $3k in cash as well as a laptop. The laptop and around $1,100 of the stolen cash were reportedly retrieved by the police following the arrests of the perpetrators.
