The relationships between the prosecution service and the police follow distinctive models (hierarchical or network) in accordance with the ruling procedure system (accusatorial or inquisitorial). In the system of the Islamic Republic of Iran, the hierarchical model is used in the relationship between the prosecution service and the police. Studies show that there are deficiencies in the relationship between the two organizations. The present article seeks to provide an optimal model of the relationship between the prosecution service and the police in the Islamic Republic of Iran. This research has used the library methodology, and the proposed model is designed according to the existing circumstances and realities of Iran's criminal justice system and addresses its aspects. The model of prosecution service and police relations at its best situation, results in more efficiency and effectiveness in detecting, prosecuting and investigating crimes. The aspects of the optimal model for Iran's police and prosecution service relations are as follows: 1- Assignment the crime detection function to the police, 2. Two-way communication based on the network model between the two police and prosecution service and, as a result, the equality of the two organizations with each other 3. Assignment of execution of investigations to the judicial police, 4. Separation of the investigating authority based on the severity of the crimes 5. The administration of the prosecution service on the judicial police; in this way, the judicial police are established and run under the dominion of the prosecution service, and at the same time, in proportion to the circumstances, enjoy a flexible and moderate sovereignty.
