The former heads of defunct slots developer Sheriff Gaming are going to jail after being convicted of illegal gambling, money laundering and tax evasion.

On Wednesday, Dutch media reported that Stijn Flapper, Maurice Gregoire and Michel Gregoire had been sentenced to hefty prison terms for their involvement in an illegal online gambling operation that laundered up to €123m derived from a variety of other illicit activities, including – as alleged by prosecutors – drug trafficking.

Flapper (pictured), the former CEO of Sheriff Gaming’s parent company Bubble Group NV, was sentenced to two years in prison. Michel Gregoire also received a two-year stint in stripes, while his brother Maurice got off comparatively lightly with a mere 16-month sentence.

All three actually got off relatively easy, as court proceedings in October saw prosecutors request a four-year sentence for Flapper, while the Gregoire brothers were looking at up to three years behind bars.
