Nine more people have been arrested in connection with a Dutch-British investigation into sham marriages, bringing the total so far this month to 32, the public prosecution department said in a statement.

Five women and four men were picked up in raids in Groningen, Breda, Amsterdam, Lelystad, Rotterdam, Leeuwarden and Almere as part of operation Dutch Conclusion.
The nine have all been questioned and released from custody but will face charges in connection with people trafficking, the department said.
Earlier arrests
At least 23 Dutch nationals of Antillean origin and dozens of people in Britain were arrested earlier this month in the ongoing joint operation to break up the sham marriage ring.
The probe focused on weddings involving illegal Nigerian men and women with Dutch nationality. The women, from the former Dutch Caribbean colonies, were recruited in the Netherlands and flown to Britain to get married.
Once married, the Nigerian grooms had legal residency and access to social security provisions, the Dutch public prosecutor said in a statement. The women were paid between €2,500 and €3,500 for their role.
