Kernrechtsfrage
Whether the pretrial detention could be maintained on the basis of collusion risk.
Extrahierter Entscheid
Yes. The circumstances, including prior conduct during the investigation, psychiatric findings, and the relationship to the key witness, provided sufficiently concrete indications of significant collusion risk.
Extrahierte Begründung
The Court held that mere theoretical risk is insufficient, but here concrete indicators existed: threatening and manipulative behavior, disruption during police questioning, personality traits increasing the risk of intimidation, and the sensitive witness situation. Less intrusive measures were not adequate at this stage.
