Key legal question
Whether the police interrogations before formal opening of the investigation were unlawful and unusable
Extracted holding
The police were allowed to question the detained suspect and conduct immediate inquiries within 24 hours; the report to the prosecutor was timely.
Extracted reasoning
Police must carry out urgent initial investigative steps after a detention and may question the suspect about identity and the offense. A formal report to the prosecutor is required once a sufficiently concrete suspicion exists, which arose only after the initial questioning.
