When can a private citizen make a citizen's arrest in Colorado?
1. Statutory Authority
Colorado codifies citizen's arrest at Colo. Rev. Stat. § 16-3-201: "A person who is not a peace officer may arrest another person when any crime has been or is being committed by the arrested person in the presence of the person making the arrest."
2. Felony Standard
For felonies committed in the citizen's presence, § 16-3-201 directly applies. For past felonies not committed in the citizen's presence, Colorado common law permits arrest where a felony actually occurred and reasonable cause exists.
3. Misdemeanor Standard
Section 16-3-201 covers "any crime" committed in the citizen's presence, including misdemeanors. This is broader than many states, though courts construe "in presence" strictly.
4. Georgia Post-Arbery Comparison
Georgia repealed its broad citizen's arrest statute via HB 479 in May 2021 after Ahmaud Arbery's killing. Colorado has not modified § 16-3-201.
5. Force Permitted
Colo. Rev. Stat. § 18-1-707 governs force in arrest. A private person may use reasonable force, but deadly force by a private person is restricted to self-defense circumstances under § 18-1-704 (defense of person) or § 18-1-704.5 (Make My Day - home defense).
6. Hand-Off Duty
The arrestee must be delivered without unnecessary delay to a peace officer.
7. Risks
False imprisonment (Colo. Rev. Stat. § 18-3-303), second-degree kidnapping (§ 18-3-302), assault, and civil tort liability.
8. Shopkeeper's Privilege
Colo. Rev. Stat. § 18-4-407 authorizes merchants and their employees to question and detain a suspected shoplifter on probable cause in a reasonable manner for a reasonable time, with immunity from civil/criminal liability.
9. Stand-Your-Ground / Castle Doctrine
Colo. Rev. Stat. § 18-1-704.5 ("Make My Day") provides expansive home-defense immunity. Separate from arrest authority.
10. Practical Recommendation
Colorado attorneys recommend calling 911. While the statute is broader than many, miscalculations expose the citizen to second-degree kidnapping charges.
