Jan-Dirk Paarlberg, a 67-year-old real estate entrepreneur from Maarssen, has been arrested by the Dutch Public Prosecution Service due to an outstanding debt of €15 million owed to the Dutch State. Officially categorized as ‘in detention’, Paarlberg has one year to settle the debt. In 2019, the Supreme Court ruled that he must pay €24 million after being found guilty of laundering millions extorted by Willem Holleeder from real estate dealer Willem Endstra, who was known as a banker in the underworld.
