Cybercrime and Law Enforcement in Tanzania: Prospects and Challenges in Investigation and Prosecution

Abstract

Cybercrime investigations depend on electronic records that are volatile, easily replicated, and frequently distributed across devices, service providers, and national borders. Tanzania has established a substantial legal and institutional framework through the Cybercrimes Act, the Evidence Act, the Electronic Transactions Act, communications legislation, data-protection law and specialised enforcement bodies. The central problem is therefore not the absence of law, but the interaction of fragmented statutes, operational rules and institutional capacity. Using a doctrinal method, this article analyses legislation, regulations, selected Tanzanian decisions, the National Prosecutions Service’s 2025 standard operating procedures, recent judicial practice rules and relevant scholarship. It situates its contribution against existing Tanzanian literature on jurisdiction, admissibility and institutional capacity, and argues that Tanzania’s strongest prospects lie in express statutory recognition of electronic evidence, investigative preservation and production powers, specialised policing and prosecution arrangements, developing case law, and emerging international cooperation. Persistent challenges nevertheless arise in the authentication and attribution of data, documentation of chain of custody, uneven forensic capacity, rights-sensitive access to subscriber information, prosecutorial case design, judicial treatment of technical proof, primary-court receivability of electronic evidence and timely acquisition of evidence held abroad. The article recommends comprehensive and court-applicable digital-evidence rules, uniform interagency chain-of-custody standards, early prosecutorial involvement, sustained technical training, accredited forensic capability, transparent service-provider protocols and stronger international cooperation, arguing that these reforms should improve both effectiveness and legitimacy by pairing technical reliability with privacy, fair-trial and due-process safeguards.
