Kernrechtsfrage
Whether continued security detention was justified by collusion risk after the investigation had been closed.
Extrahierter Entscheid
The collusion risk was no longer sufficiently concrete to justify continued detention; milder measures could adequately address it.
Extrahierte Begründung
The investigation was completed and the main evidence secured, so higher requirements applied. Any remaining risk of influencing the complainant was limited and could be neutralized by a contact and area ban.
