An arrest warrant is a legal document issued by a judge or magistrate that authorizes law enforcement to arrest a specific individual. It is typically based on evidence or probable cause that the person has committed a crime. The warrant must include details such as the person's name, the alleged offense, and the jurisdiction where the arrest can take place. Once an arrest warrant is issued, police officers can apprehend the individual named in the warrant. This process ensures that arrests are made lawfully and protects the rights of the accused. If the person is arrested, they will usually be taken into custody and brought before a court to face charges related to the warrant.
