According to sources, he was arrested on the basis of decrypted messages from a downed computer server that Jos Leijdekkers also used. It is still unclear which server exactly is involved.
The Dutch and Turkish authorities have been trying to close the net around Jos Leijdekkers for a long time. The Dutchman is one of the largest players in the Belgian-Dutch cocaine trade. He is the most wanted fugitive in the northern neighbors.
He is particularly suspected of large-scale cocaine trafficking, excessive violence and money laundering. Justice also accuses him of involvement in the disappearance of Naima Jillal, who was kidnapped from her luxury apartment in Amsterdam in October 2019 and was almost certainly tortured and murdered.
