Concept:The Nigeria Police Force is classified as an agency working under the executive arm of government.
Explanation:The executive arm of government is responsible for carrying out and enforcing the laws made by the legislature.
The Nigeria Police Force is one of the law-enforcement agencies used by the executive to maintain public order and safety.
It is not an agency of the judicial arm, because the judiciary interprets laws and settles disputes in court.
It is also not under the Ministry of Defence, which is concerned with the armed forces and external defence.
Although the Ministry of Interior is an executive ministry, the correct broad classification of the police is the executive arm of government.
Therefore, the police perform executive functions by enforcing laws and safeguarding the public.
