I find it less clear what exactly the article is alleging. It refers to a police practice, and says that a judge can extend it further, but the press release says that the police did not apply this practice. And no information is given about what the substance of the district court's decision was. But all that said, my initial read on the article, "put a total of 27 supporters of the group in prison" is that the police are grabbing innocent people and putting them in preventative detention, but that does not appear to be supported by the article. Rather they are being held for minor crimes (which I don't think anyone is contesting that they committed) and being kept there (the article says "prison" but I don't know whether Germany has the same distinction at the US between prison and jail/pre-trial detention).
