An arrest warrant is a warrant issued by and on behalf of the state, which authorizes the arrest and detention of an individual.
Once the warrant has been issued section 29 of the Code requires that the arresting officer must give notice to the accused of the existence of the warrant, the reason for it, and produce it if requested.
The issue of Arrest Warrants in the United Kingdom is governed by section 1 of the Magistrates' Courts Act 1980. A warrant may only be issued by a Justice of the Peace based upon evidence in writing and sustained under oath and for adults if the suspected offence is either indictable or punishable by imprisonment; or the address of the suspected offender cannot be ascertained in order that he may be issued with a summons.
In the United States, an arrest warrant must be supported by a signed and sworn affidavit showing probable cause that:
Hence, the form and content of an arrest warrant may be similar to the following:
In most jurisdictions, an arrest warrant is required for misdemeanors that do not occur within view of a police officer. However, as long as police have the necessary probable cause, a warrant is usually not needed to arrest someone suspected of a felony.
A bench warrant, sometimes also called a "writ of capias" or "capias," is a variant of the arrest warrant. A bench warrant usually commands the arrest of someone for failing to show for a required court appearance.
An example of the usage of this word is as follows: "... Thomas Fraser, Gregor Van Iveren and John Schaver having some time since been Confirmed by the Committee of the County of Albany for being Persons disaffected to the Cause of America and whose going at large may be dangerous to the State, Ordered Thereupon that a Mittimus be made out to keep them confined till such time as they be discharged by the Board or any other three of the Commissioners."

Commonly (but not always), the person who is subject to a bench warrant has intentionally avoided a court appearance to escape the perceived consequences of being found guilty of a crime. If a person was on bail awaiting criminal trial when the non-appearance took place, the court usually forfeits bail and may set a higher bail amount to be paid when the subject is re-arrested, but normally the suspect is held in custody without bail. If a person is found to have a bench warrant against him or her when stopped by a law enforcement officer, the person is immediately taken into custody by authorities, rejailed and a hearing is held at which time new bail amount and conditions are set and a new court appearance date is scheduled. Often, if a person is arrested on a bench warrant, that person is held without bail until he or she can appear in court for whatever incident it was that he or she failed to appear to address originally. Such a person is referred to as a "flight risk", meaning that there is a high likelihood that he or she will flee and not appear for the assigned court date (for a second time).
Bench warrants are traditionally issued by sitting judges or magistrates.
