Authorities in Malaysia are stepping up the fight against the growing number of illegal electronic gambling centers that they say have sprouted in the country.

Last week, police busted eight gambling centers operating under the guise of clubs that promoted sports like pool, snooker and soft darts in Kuala Lumpur’s Cheras district. Authorities seized gambling machines worth RM500,000 (USD112,599) from the clubs, local news outlets reported.

In an interview with Malay Mail, City Hall enforcement director Abdul Salim Mansor said they have conducted 517 raids since last October, noting that “this was the department’s first raid for this year.”

The “mushrooming” number illegal gambling activities in the country has also prompted the Federal Territories Ministry, which oversees the administration and development of Kuala Lumpur, Labuan and Putrajaya territories, to “enforce stricter rules.”
