The relevance of the article is that the issue of organization and tactics of covert investigative actions in the theory of criminology is a fairly new concept, because this kind of investigative (investigative) actions in the CPC of Ukraine appeared only after reforming procedural legislation in 2012. Prior to this period, such covert means were not under the legal regulation of criminal procedural law, and their tactical principles were studied mainly in the theory of operational and investigative activities. After these novelties of the CPC of Ukraine, among scientists of the theory of criminology there was a task to develop new tactical recommendations on the tactical features of covert investigative actions. The article examines the organization and tactics of certain covert investigative actions in the investigation of fraud in the field of tourism, committed by an organized group, including seizure of correspondence, knowledge of transport telecommunications networks, removal of information from electronic information systems. Based on the study of different points of view of scientists, the author concluded that the tactics of covert (investigative) actions have their own characteristics and differ from the tactics of investigative actions, in particular because of their secret nature. The author highlights situations in which conducting covert investigative actions in the investigation of fraud in the field of tourism, committed by an organized group, is appropriate. The main tactical features of the seizure of correspondence, removal of information from transport telecommunications systems, removal of information from electronic information systems are outlined. When investigating fraud in the field of tourism, committed by an organized group during these covert investigative (search) actions, the following information relevant to the investigation may be established: 1) on the use of sightseeing and tourist tours for illegal employment, emigration from the country; 2) about travel companies - one-day; 3) on the real state of affairs in the travel agency and on possible tax evasion, inaccurate tax reporting; 4) evasion of insurance payments or non-existent insurance payments; 5) on possible illegal use of personal data, illegal payment transactions, including with bank loans, etc.
