Key legal question
Whether the cantonal authority correctly found a risk of collusion justifying continued detention
Extracted holding
No. The record did not show concrete present indications of collusion; prior conduct and a later SIM-card possession were insufficient.
Extracted reasoning
After the investigation had essentially been completed, a collusion ground required particularly careful scrutiny. The authority relied on earlier use of code language and on conduct predating or occurring after the investigation, but these facts did not establish current concrete danger to evidence-taking.
