Key legal question
Whether a valid criminal complaint had been filed for the minor theft against A_________.
Extracted holding
A valid complaint existed because the victim signed a written complaint before the police within the time limit and never withdrew it.
Extracted reasoning
Swiss complaint law has no formal requirements beyond timely filing with the competent authority and an unconditional wish to prosecute. The victim's later statements and letters confirmed that his initial hesitation was due to fear, not lack of intent to prosecute.
