The police made five other arrests in Amsterdam, Huis ter Heide, Utrecht and Vianen on Monday evening in addition to the arrest of the sister of the criminal Ridouan Taghi. According to the national police unit, these are people who would belong to the organization of Taghi.

It was announced on Monday evening that one of Taghi's sisters was arrested in Vianen in the area where Taghi grew up. Police and OM see an important role for the Taghi family who were arrested in Dubai on Monday morning.

Two of his sisters have been interrogated by the police before. Two brothers are in prison in Morocco. And earlier this month, Taghi's cousin was also arrested in the investigation into the murder of lawyer Derk Wiersum. The family members would mainly form a link between Taghi and the perpetrators of crime.

Following Monday's arrest of Taghi in Dubai, a total of eight house searches were made and six suspects arrested. In addition to Taghi's sister, there are five men between the ages of 29 and 45. The searches were in Amsterdam, Huis ter Heide, Utrecht and Vianen. The suspects have been arrested for money laundering, possession of weapons and possession of drugs.

Detective chief Andy Kraag of the national investigation said on Monday that with the arrest of Taghi the operation against the top criminal is far from over. "We're going to dismantle the entire organization," Kraag said yesterday.
