The three raids were conducted at a café and its adjoining house.
In total, 22 people were found in attendance and over €12,000 cash was seized as well as one Rolex. 19 illegal slot machines were seized by the KSA which were later disposed of – one of which showed a monthly turnover of €100,000.
Of the 22 people found, two of them were arrested for money laundering.
Venlo’s mayor Antoin Scholten said: “Tackling illegal gambling is important to Venlo. With this we protect our young people, we give criminals no chance of money laundering and we stop breeding grounds for possible drug trafficking.
“Moreover, these criminal activities cause a lot of unrest and nuisance in the area. We will continue to take action against that.”
This is the second illegal gambling raid conducted by the KSA in the last week, following action being taken in Velsen and Spain.
