This study assessed how police training influences the technical competence of officers in the Directorate of Criminal Investigations handling cyber fraud cases in Nairobi City County. It also examined challenges that limit the effectiveness of such training and reviewed measures used to strengthen cyber fraud investigation capacity. The study used a descriptive research design and a mixed-methods approach. The target population was 200 DCI officers serving in Nairobi City County, drawn from the Financial and Banking Fraud Investigations Unit, Cybercrime Unit, and Crime Research and Intelligence Bureau. Stratified random sampling was used to select 60 officers. Fifty-four officers returned usable questionnaires, giving a 90% response rate. Data were collected through semi-structured questionnaires and key informant interviews. Quantitative data were analysed descriptively using SPSS version 26, while qualitative data were analysed thematically. The findings showed that 85.2% of respondents agreed that the quality of police training affects the competence of DCI officers in cyber fraud investigations. Technical competence also influenced investigation effectiveness, with 55.6% reporting a great effect and 33.3% reporting a moderate effect. In addition, 88.9% agreed that technical and knowledge-related challenges hinder effective cyber fraud investigations. There was strong support for advanced cyber analytic tools in training, with 81.5% agreeing that more emphasis should be placed on such tools. However, support for monitoring suspect behaviour online was lower, at 55.5%, while 35.2% disagreed, pointing to legal, ethical, practical, or capacity-related concerns. The study adds evidence from Nairobi City County on the relationship between police training, technical competence, and cyber fraud investigation performance. It shows that training is important, but its value depends on practical exposure, access to current investigative tools, digital forensic support, and clear procedures for online monitoring and digital surveillance. By focusing on DCI officers working in financial fraud, cybercrime, and intelligence-related units, the study gives context-specific insight into capacity gaps in cybercrime policing in Kenya. In practice, the study recommends targeted curriculum reform, continuous professional development, decentralization of digital forensic services, increased funding for cyber-investigation infrastructure, and clearer operational guidelines for online monitoring. These measures would improve the quality, speed, and reliability of cyber-fraud investigations. In theory, the study reinforces the view that specialized training and technical competence are central to effective cybercrime investigation. It also shows that police training models must keep pace with technological change, emerging forms of cyber fraud, and the legal and ethical demands of digital investigations.
