ABSTRACT
Before the criminal justice process can begin, a person must come within
the custody and control of the law. In some instances, an arrest immediately
follows a detention-for example, when a person is detained and the officer
discovers additional information that gives him or her probable cause to
make an arrest. But when the officer has probable cause to make an arrest
without a warrant, is acting under a warrant, or has witnessed an offense per-
sonally, he or she may make the arrest immediately.
