In April of last year, the Dutch police service announced it had arrested a man who allegedly ran a company selling custom PGP BlackBerrys—security-focused BlackBerry devices that are supposedly heavily used by organized crime groups. Toronto Police also seized a server belonging to the company.

Now, Dutch police say they have managed to decrypt a number of messages stored on that server, despite the messages supposedly being protected with end-to-end encryption.

By decrypting the messages, authorities have gained access to evidence for dozens of investigations into "assassinations, armed robbery, drug trafficking, money laundering, attempted murder and other organized crime," a translated version of a press release from Openbaar Ministerie (the Public Prosecution Service) reads. The body claims to have "access to 3.6 million encrypted messages within organized crime."
