Key legal question
Whether pretrial detention could be maintained on the ground of collusion risk
Extracted holding
Yes. Concrete indications showed a serious risk that the defendant could influence witnesses, coordinate statements, or conceal evidence.
Extracted reasoning
The court relied on pending investigative acts, the defendant's prior disregard of a contact ban, his attempt to send a covert letter, and inconsistent statements. Abstract possibilities were insufficient, but the concrete facts justified detention.
