Criminal law in Peru identifies acts that the state treats as crimes and sets possible consequences. The system also explains how authorities investigate, charge, try, and decide a case. The Código Penal describes crimes and sanctions, while the Código Procesal Penal describes much of the procedure. The exact legal classification depends on facts, evidence, intent, harm, and circumstances. The Policía Nacional del Perú may receive reports, protect people, gather initial information, and carry out acts under the direction of the competent authorities. The Ministerio Público, through the Fiscalía, leads or directs the prosecution of many criminal cases. The Poder Judicial provides judicial control and decides cases through judges. A judge may also decide questions about restrictions on liberty, evidence, protection, and other important procedural issues. A case can begin with a denuncia made to the police or Fiscalía. Authorities may then conduct preliminary inquiries, collect statements and records, order or request expert work, and decide whether the evidence supports a formal prosecution. A person accused of a crime has important rights, including the right to know the accusation, remain silent, receive legal assistance, and be treated as innocent until a final decision says otherwise. Victims may report harm, seek protection, participate through the available procedures, and request reparation. Evidence should be preserved carefully and lawfully. Messages, photographs, medical records, financial records, objects, and witness details may matter, but changing or inventing evidence can create a serious new problem. Criminal matters can involve urgent risks, detention, violence, or deadlines that are not safe to guess. A person should seek a criminal lawyer quickly, avoid discussing the facts publicly, keep every official document, and follow lawful instructions from the authorities.
