Daan C., in possession of an extensive criminal record, is considered the main suspect in a criminal case that also involves three other men. The foursome is suspected by prosecutors of large-scale trafficking in weapons and drugs and of laundering criminal money. Certainly in the case of Daan C., those suspicions can be traced primarily to the chat messages he exchanged on his encrypted Encrochat phone. After the police managed to hack the Encrochats phones, they saw on Daan C.'s phone quite a number of messages about weapons (hand grenades, machine guns) and the production of drugs.
