Key legal question
Whether pretrial detention was lawful because of a concrete flight risk
Extracted holding
Yes. Given the accused's lack of ties to Switzerland, illegal stay, no family or work, and indications he wanted to leave for Greece, a concrete flight risk existed.
Extracted reasoning
Flight risk is assessed by all relevant personal circumstances. The accused had no meaningful attachment to Switzerland; his arguments did not make flight improbable, and the fact that he had not fled earlier was insufficient to dispel the risk.
