German security officials announced on 6 July 2021 that they had made more than 750 arrests and seized large quantities of drugs after gaining access to the encrypted chats of EncroChat mobile phones.[1][2] The investigation had started in April 2020 and focused on users of the EncroChat service involved in the illegal drug trade, according to Frankfurt prosecutors and the Federal Criminal Police Office (BKA).[1][2]

Investigators seized 3.2 metric tonnes of cannabis, alongside about 320 kg of synthetic drugs, more than 125,500 ecstasy pills, almost 400 kg of cocaine and 10 kg of heroin.[1][2] They also confiscated 310 weapons, more than 12,200 rounds of ammunition and assets worth 168 million euros.[1][2]

The EncroChat data came from a French investigation in which French and Dutch authorities set up a joint team that decrypted the network’s communications.[1][2] Frankfurt prosecutor Julia Bussweiler said the investigation was far from over, with many suspects in pre-trial detention while the seized data was checked for indictments.[1][2]
