Detention is the process when a state, government or citizen lawfully holds a person by removing their freedom of liberty at that time. This can be due to (pending) criminal charges being raised against the individual as part of a prosecution or to protect a person or property. Being detained does not always result in being taken to a particular area (generally called a detention centre), either for interrogation, or as punishment for a crime (see prison).

Détain-et-Bruant est une commune française, située dans le département de la Côte-d'Or et la région Bourgogne.
