Hong Kong police have broken up what they believe was a sophisticated gambling syndicate behind a network of underground casinos that used arcade machines for betting games.
Detectives believe the racket, run by a gang from Hunan province on the Chinese mainland, had raked in more than HK$14m (US$1.8m) from its eight betting establishments in Mong Kok and Sham Shui Po in the past six months.
One police source said its command centre was set up in Mong Kok to collect business takings from the keepers of its gambling dens each night.
