The police arrested two suspected drug traffickers in Bremen last week.
The public prosecutor's office had discovered the suspects by evaluating the so-called Encrochat data, the police said on Monday.
Between the end of March and the end of June 2020, a 35-year-old and his 31-year-old accomplice are said to have imported several hundred kilograms of cannabis from Spain to Germany and sold it in Germany.
Bremen - The police in the Netherlands and France managed to skim off more than 20 million encrypted messages from the provider of crypto cell phones Encrochat last year.
The service was considered unbreakable because of its extensive encryption.
Cell phones and chat software from the provider were mainly used by criminals.
