Kernrechtsfrage
Whether pre-trial detention could be continued on the basis of collusion risk under Zurich criminal procedure law.
Extrahierter Entscheid
Yes. The court held that concrete indications of collusion existed and that the authorities could continue detention on that ground.
Extrahierte Begründung
The appellant's prior conduct toward third parties and witnesses showed a concrete risk of pressure and interference with the truth-finding process. A mere theoretical possibility would not suffice, but the file contained specific indications. Because collusion risk was established, the court did not need to examine flight risk.
