Custody, often referred to as detention, is the legal process where an individual is held in a secure facility, typically by law enforcement or judicial authorities. This can occur during an investigation or after an arrest, ensuring that the person remains available for legal proceedings. Custody can apply to both adults and minors, with specific regulations governing each group. During custody, individuals may be held in various settings, such as police stations or juvenile detention centers. The duration of custody can vary based on the circumstances of the case, including the nature of the alleged offense and the legal requirements surrounding bail and court appearances.
