The federal indictment of 15 alleged antifa cell members in Minnesota on conspiracy charges last week is sending antifa’s leaders into a panic, scrambling over the case’s legal implications for the underground movement.

In response to last week’s raids on the residences of the defendants, allied antifa accounts across social media started circulating an alert warning others, “One of our comrades was arrested and all of their electronics were confiscated. Please alert all of your groups. Stay safe.”
