Immigration officerAn immigration officer is a law enforcement official whose job is to ensure that immigration legislation is enforced. This can cover the rules of entry for visa applicants, foreign nationals or those seeking asylum at the border, detecting and apprehending those that have breached the border and removing them, or pursuing those in breach of immigration and criminal laws. In the United Kingdom, immigration officers are present in the Border Force and Immigration Enforcement – both law enforcement commands of the Home Office – and the National Crime Agency.
SummonsA summons (also known in England and Wales as a claim form and in the Australian state of New South Wales as a court attendance notice (CAN)) is a legal document issued by a court (a judicial summons) or by an administrative agency of government (an administrative summons) for various purposes. A judicial summons is served on a person involved in a legal proceeding. Legal action may be in progress against the person, or the person's presence as witness may be required.
Citizen's arrestA citizen's arrest is an arrest made by a private citizen – that is, a person who is not acting as a sworn law-enforcement official. In common law jurisdictions, the practice dates back to medieval England and the English common law, in which sheriffs encouraged ordinary citizens to help apprehend law breakers. Despite the practice's name, in most countries the arresting person is usually designated as a person with arrest powers, who need not be a citizen of the country in which they are acting.
Law enforcementLaw enforcement is the activity of some members of government who act in an organized manner to enforce the law by discovering, deterring, rehabilitating, or punishing people who violate the rules and norms governing that society. The term encompasses police, courts, and corrections. These three components may operate independently of each other or collectively, through the use of record sharing and mutual cooperation. Throughout the world, law enforcement are also associated with protecting the public, life, property, and keeping the peace in society.
