Dutch police have picked up a further six people in the Netherlands following the arrest of the Netherlands’ most wanted man, Ridouan Taghi, in Dubai on Monday.

The arrests were made  during raids on private homes in Amsterdam, Utrecht, Vianen and Huis ter Heide. Five men and one woman were arrested, ranging in age from 29 to 45. They are suspected of money laundering, weapons offences and the possession of hard drugs.

According to the Telegraaf, the woman is Ridouan Taghi’s sister.

Taghi was arrested at a private home in Dubai following intensive international cooperation with the Dubai police. The Dutch public prosecution service has made a formal request for his extradition.

Taghi is the main suspect in a gangland trial involving five murders and several attempted murders in a case known as Marengo, which is due to start in March. The brother of crown witness Nabil B is one of the murder victims.

Shurandy S, the man who shot his brother dead, was sentenced to 28 years in jail on Monday, but Taghi is suspected of ordering the killing. He is also thought to be behind the murder of lawyer Derk Wiersum, who was representing Nabil B in the ongoing investigation. That murder is not part of the Marengo trial.

The Telegraaf says Taghi’s family have an important role in his crime gang. Two of his sisters have been previously questioned by police, two brothers are in jail in Morocco and a nephew has been arrested in connection with the murder of lawyer Derk Wiersum.
