§ 22-1. When arrests may be made without warrant.
(a)
An officer or private person may arrest any person without warrant, for an indictable offense committed, or a breach of the peace threatened or attempted in his presence; or when a person has committed a felony, though not in his presence; or when a felony has been committed, and he has reasonable grounds to suspect and believe the person proposed to be arrested to have committed it; or on a charge, made upon reasonably cause, of the commission of a felony by the party proposed to be arrested. And in all cases of arrests without warrant, the person making such arrest must inform the accused of the object and cause of the arrest, except when he is in the actual commission of the offense or is arrested on pursuit.
(b)
Any law enforcement officer may arrest any person on a misdemeanor charge without having a warrant in his possession when a warrant is in fact outstanding for the person's arrest and the officer has knowledge through official channels that the warrant is outstanding for the person's arrest. In all such cases, the officer making the arrest must inform such person at the time of the arrest the object and cause therefor. If the person arrested so requests, the warrant shall be shown to him as soon as practicable.
