An arrest occurs when an individual is taken into custody and is no longer free to leave. A person can be placed under arrest without ever being handcuffed. An arrest involves some type of submission, whether voluntary or involuntary, to a Police Officer. Arrests typically occur after a Police Officer witnesses a crime, after probable cause to make an arrest has been established, or after an arrest warrant has been executed. Depending on the crime and arresting agency, the subject is either cited to Court and released or transported to jail.
