Key legal question
Whether the thefts were committed as a member of a band under Art. 139(3) StGB
Extracted holding
Yes. The group formed a stable team with a sufficient organizational minimum and a continuing, at least implicit, agreement to commit multiple thefts.
Extracted reasoning
Band membership does not require a formal criminal pact; a convergent, repeated will to cooperate in future thefts suffices, even if membership and concrete offenses vary and not all members participate in each act.
