Statistics on juvenile delinquency indicate that over the past decade, the level of serious and especially serious crimes committed by these individuals has remained relatively stable. In such a situation, the important tasks of law enforcement agencies are the timely detection and suppression of crimes committed by minors and their removal from the criminal environment through individual prevention. Effective solution of these tasks is impossible without the implementation of operational investigative activities. In this regard, a study was carried out regarding participation of minors in operational search relations in two main roles: as persons providing assistance to subjects of operational search activities and as objects of operational search activities. Within the framework of the first direction, legislative regulation of the conditions for the provision of assistance to minors is proposed: written consent of legal representatives and minors themselves, if they have not reached the age of 16; ensuring the safety of minors by employees of the operational unit; the introduction of additional safeguards for the assistance of minors. Within the framework of the second direction, proposals have been prepared concerning the conditions for conducting operational investigative measures against persons under the age of criminal responsibility. The issue of the need to involve legal representatives and teachers in conducting a public survey of minors was also raised for academic and practical discussion.
