Dutch gaming regulators are probing whether unauthorized online sports betting operators are using cash machines to facilitate account transactions.

On Tuesday, the Netherlands’ Kansspelautoreit (KSA) regulatory body announced that it had teamed up with the Public Prosecution Service to raid an unspecified company’s place of business and two private homes in search of evidence of an unauthorized online sports betting business.

The KSA said the raids were the result of tip-offs it received one year ago regarding the suspected use of Cash Centers – vending machines offering online payment services – to facilitate online sports betting account deposits and withdrawals.

The KSA stated that its investigation centered on 15 suspects supposedly linked to these machines, although no arrests were made in the course of Tuesday’s raids. These 15 individuals are suspected of having ties to internationally licensed online gambling operators who accept Dutch customers despite the lack of KSA approval.
