Cambodian authorities have taken down a Malaysian/Chinese illegal online gambling ring operating in the border town of Poipet.

On Wednesday, the Khmer Times reported that police in Banteay Meanchey province had arrested 55 foreign nationals – 47 of which were Malaysian, the rest Chinese – in a series of raids on two villas in Poipet on Tuesday.

Police were reportedly tipped to the illegal operation after locals noted that, while the villas were stuffed with people, they only emerged at night, apparently too busy during the day taking wagers from customers in their home countries.

Poipet city police Major Sok Bora told the media outlet that the simultaneous raids on the two villas had caught the suspects in the act of operating their illegal betting business and police had seized the now standard assortment of computers, mobile phones and other tools of the trade.
