This study evaluates the CRU’s effectiveness using the United Nations Office on Drugs and Crime assessment criteria for internal police complaint systems. The findings reveal that while CRU successfully serves as a bridge to improve the police-citizen relationship and its use of digital technologies leads to greater accessibility to trained officers to resolve complaints, however, critical deficiencies undermine its effectiveness. Transparency gaps fail to provide adequate public information about investigative processes and disciplinary outcomes. The unit’s organisational structure remains opaque with unclear procedures, while digital divide challenges limit rural access. The study’s recommendations include enhancing transparency through detailed public reporting, developing public accessible operational manual, and clarifying legislative mandates to strengthen police-citizen trust.en© The Author(s) 2025.
