1. Nigeria Police Force. 2. Police – Nigeria. 3. Law enforcement – Nigeria Law On Prevention And Detection Of Crimes By The Police In Nigeria is a doctrinaire research which was successfully undertaken by the author at the Faculty of Law of Ambrose Alli University, Ekpoma, Edo State. Expectedly, the treatise has a robust research base on which the superstructure of the legal and legislative epistemology regarding prevention and detection of crimes by the Nigeria Police is established. And, this is identifiable from the beginning of the book to its very conclusion, which, as the author remarks, draws information from both primary and secondary sources.
