What do you mean no connections to the military? Some of the arrested are still in the military right now, another one was part of our special military forces.

there were no weapons found

Maybe it did not come up initially, but now it is comminicated that they actually possessed weapons, quote:

Bei rund 50 Objekten seien auch Waffen festgestellt worden.

Weapons were also found in about 50 objects, he said.

The rest is odd though, there has been an interview with an MP from the Left party where they discuss what you mentioned.
