When can a private citizen make a citizen's arrest in Massachusetts?

Question

Accepted Answer

1. Statutory Authority   Massachusetts has no broad citizen's arrest statute. Authority derives from common law ( Commonwealth v. Lussier , 333 Mass. 83 (1955)). The felony definition is set at   Mass. Gen. Laws ch. 274, § 1  .    2. Felony Standard   A private person may arrest without warrant for a felony actually committed in their presence. Massachusetts case law also recognizes arrest for a felony actually committed when probable cause exists, though courts are strict.    3. Misdemeanor Standard   Massachusetts common law generally does not allow private arrest for misdemeanors, though some authority exists for breach-of-peace offenses committed in the citizen's presence.    4. Georgia Post-Arbery Comparison   Georgia repealed its broad citizen's arrest statute via   HB 479   in May 2021 after Ahmaud Arbery's killing. Massachusetts has not enacted comparable reform but its common-law doctrine is already narrow.    5. Force Permitted   Force must be reasonable. Massachusetts does not recognize stand-your-ground (it has a duty-to-retreat outside the home,  Commonwealth v. Shaffer , 367 Mass. 508 (1975)), and deadly force by private citizens is sharply restricted to self-defense.    6. Hand-Off Duty   The arrestee must be promptly turned over to a law enforcement officer.    7. Risks   Kidnapping (Mass. Gen. Laws ch. 265, § 26), assault and battery, and civil tort exposure for false arrest, false imprisonment, and battery.    8. Shopkeeper's Privilege     Mass. Gen. Laws ch. 231, § 94B   provides merchants a defense to false imprisonment claims when they have reasonable grounds to believe a person has committed shoplifting and detain in a reasonable manner.    9. Stand-Your-Ground / Castle Doctrine   Massachusetts requires retreat outside the home.   Mass. Gen. Laws ch. 278, § 8A   codifies the castle doctrine within the dwelling.    10. Practical Recommendation   Massachusetts attorneys consistently advise calling 911. The narrow common-law authority and lack of stand-your-ground make citizen's arrest particularly risky.
