Legal analysis: if the loan is not repaid, the police will not file a case. Being rich is not a civil dispute, and the public security organs are mainly responsible for criminal cases and public security management. Therefore, owing money does not fall within the jurisdiction of the public security organs, and the police will not file a case for handling. The parties can solve the problem through consultation, 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.
Legal basis: Article 1 of the Civil Procedure Law of People's Republic of China (PRC), when the plaintiff files a lawsuit in a people's court or the defendant files a counterclaim, relevant evidential materials that meet the conditions for prosecution shall be attached.
