A police officer’s duties are set by law rather than by an employer’s job description. In South Africa the South African Police Service has a constitutional mandate to prevent, combat and investigate crime, maintain public order, protect and secure the people of the Republic and their property, and uphold and enforce the law. Everything an officer does day to day sits under that mandate.
This guide sets out police officer duties and responsibilities in plain language, the shape of a shift, and how the work differs by unit. It sits in the Security Safety duties and responsibilities cluster, part of the wider job duties guide.
What Does a Police Officer Do?
A police officer responds to complaints and incidents, patrols to deter and detect crime, takes statements, investigates, makes arrests where the law allows, secures evidence and scenes, and gives evidence in court. Much of the job is written work, because a case that is not properly documented is unlikely to succeed.
Officers also carry duties towards the public that shape how the work is done, including treating people with dignity, using only the force that is reasonable and necessary in the circumstances, and informing people of their rights.

Frequently Asked Questions About Police Officer Duties
What are the main duties of a police officer?
Preventing and combating crime, investigating crime, maintaining public order, protecting people and property, and upholding and enforcing the law. In practice this means patrolling, responding to complaints, taking statements, securing scenes, investigating, making lawful arrests, completing records and giving evidence in court.
What are five duties of a police officer?
Five that cover most of the work: patrol the area to prevent crime; respond to complaints and attend scenes; take statements and open case dockets; investigate and gather evidence; and give evidence in court. Treating the public with dignity and using only reasonable force run through all of them.
What is the difference between a police officer and a security officer?
A police officer holds statutory powers, including powers of arrest and investigation, and acts under the law. A private security officer works under a contract and site instructions, with powers that come from ordinary law and consent rather than from a policing mandate.
What qualifications do you need to become a police officer?
Entry requirements are set by the South African Police Service and typically include citizenship, a minimum school qualification, age limits, no criminal record, medical and physical fitness, and completion of basic training. Check the current official recruitment requirements, as they are updated from time to time.
