Police officials are entrusted with the power to arrest a person without having obtained a warrant of arrest from a judicial officer. It is necessary for the police to have this far-reaching power as the requirements of their work (e.g. to stop a person from committing a crime) necessitate that. However, the deprivation of liberty is a serious intervention in a person’s life and the authority to arrest without a warrant must therefore be used in a lawful manner and not to intimidate, scare or punish people.
