Ridouan Taghi (born 20 December 1977) is a Moroccan-Dutch criminal. He is currently held at Nieuw Vosseveld for suspected involvement in at least ten murders related to organised crime, as well as for his involvement in drug trafficking and the leading of a criminal organisation. Until his late 2019 arrest in Dubai, Taghi was the most wanted criminal in the Netherlands with a record-breaking reward of €100,000.
Taghi's suspected crimes include the murder of Redouan B. (brother of crown witness Nabil B.) and of Nabil B.'s lawyer, Derk Wiersum. The latter was considered an attack on the Dutch legal system.
Taghi managed to evade capture by constantly altering his appearance and using false passports and visas. He was arrested in Dubai on 16 December 2019. As the Netherlands does not have an extradition treaty with Dubai, Taghi was deported three days after his arrest; based on him being declared as persona non grata by the emirate, as he had entered it under a false identity. He is being held at Nieuw Vosseveld in Vught, waiting for his trial in 2020.
