Rhode Island General Laws Title 11. Criminal Offenses § 11-47-45. Arrest and detention for possession of weapon prohibited by § 11-47-42

Every officer authorized to make an arrest for any criminal offense may arrest without complaint and warrant any person who has in his or her possession any instrument or weapon described in § 11-47-42 whenever the officer has reasonable ground to suspect that the person possesses, or is using, wearing or carrying the instrument or weapon contrary to law. Any person so arrested may be detained a reasonable time, not exceeding twenty-four (24) hours, for the purpose of making an investigation concerning the person, but no person so arrested shall be detained longer than twenty-four (24) hours without complaint being made against him or her before some proper court or justice. If the officer making the arrest shall at any time within the twenty-four (24) hours satisfy himself or herself that there is no ground for making a criminal complaint against the person, he or she shall be discharged from custody.
