Legal analysis: Public security organs are mainly responsible for criminal cases and public security management. Non-repayment of arrears is a civil debt dispute, and the parties can solve it through negotiation, litigation, arbitration and mediation. The arrears are not within the scope of police management, and the police can't handle them. However, if one party defrauds other people's property in the name of borrowing money, it may constitute fraud. At this time, you can call the police. For most loan cases, you can't report to the police, but you can only file a lawsuit or send a lawyer's letter to claim your rights.
