Police in Battambang province raided three online gambling houses in Battambang city on Sunday, arresting 17 gamblers and six staff.
A provincial police report said forces from the minor crimes office conducted the raid and confiscated evidence.
Sam Savith, deputy chief of the office, said three dens were raided for offering online gambling services.
“Our forces conducted the crackdown on three different online football betting premises at 3pm,” he said.
“We found evidence, including betting invoices and equipment for online gambling, and we arrested 23 people divided into three groups: four managers including one woman; two female cleaners and 17 gamblers.”
Mr Savith said the equipment seized from the three locations included 52 computer screens, three hard disks, 52 computer cases, two printers, 50 keyboards, 45 mouses, two calculators, 18 betting invoices and some cash.
Those arrested are still being questioned at the minor crimes office before further action is taken, he added.
“I would like all parents in Battambang to educate their children more because gambling is illegal and punishable by the law,” said Mr Savith.
“And for the den owners, please stop it because it seriously affects the children who skip school for gambling.”
