Citizen’s arrest laws in Indiana are set by statute, not common law, and they are narrower than most people assume. Under Indiana Code 35-33-1-4, a private person may arrest another only in three situations: a felony committed in your presence, a felony that has in fact occurred where you have probable cause to believe a specific person committed it, or a misdemeanor breach of peace happening in front of you where the arrest is needed to stop it.1Indiana General Assembly. Indiana Code 35-33-1-4 – Any Person Get any of those elements wrong and the arrest itself becomes a crime.
The Three Legal Grounds
The first ground is the cleanest. You personally witnessed someone commit a felony. You saw it happen.
The second is where people get in trouble. You don’t need to have witnessed the crime, but a felony must actually have occurred, and you must have probable cause pointing to the person you’re arresting. Probable cause means concrete facts a reasonable person would find convincing, not a hunch or a strong suspicion. And if it turns out no felony happened at all, the arrest is unlawful no matter how sincerely you believed otherwise.
The third ground is the narrowest. It covers misdemeanor breaches of peace — disorderly conduct, public fighting, similar active disturbances — not every misdemeanor. The breach has to be happening right then, and your arrest has to be necessary to end it. Once the disturbance stops on its own, this ground disappears.
What You Must Do After the Arrest
Indiana law requires you to notify a law enforcement officer as soon as practical and turn the arrested person over.1Indiana General Assembly. Indiana Code 35-33-1-4 – Any Person This is built into the arrest authority itself, not an afterthought. A citizen’s arrest is meant to bridge the minutes until police arrive.
Holding someone longer than needed to get an officer on scene is where these situations most often collapse. The longer you detain, the weaker your legal footing and the greater your exposure to both criminal prosecution and a civil lawsuit. Call 911 immediately. The statute does protect the officer who takes custody from false arrest or false imprisonment claims, but that protection runs to the officer, not to you.
How Much Force You Can Use
A separate statute, Indiana Code 35-41-3-3, controls force during a citizen’s arrest. You may use reasonable force to make the arrest or prevent escape, but only when a felony has been committed and you have probable cause to believe the person committed it.2Indiana General Assembly. Indiana Code 35-41-3-3 – Use of Force Relating to Arrest or Escape
Reasonable means the minimum physical intervention the circumstances require. Grabbing an arm to stop someone from fleeing is a different act from tackling a person who is standing still. Courts judge reasonableness on what you knew at the time, but force that was clearly disproportionate to the threat will not survive that review.
Deadly Force
A private citizen cannot use deadly force during an arrest unless that force would be independently justified under Indiana’s self-defense law.2Indiana General Assembly. Indiana Code 35-41-3-3 – Use of Force Relating to Arrest or Escape That means deadly force is lawful only when you reasonably believe it’s necessary to prevent serious bodily injury to yourself or someone else, or to stop a forcible felony.3Indiana General Assembly. Indiana Code 35-41-3-2 – Use of Force to Protect Person or Property
Police have broader authority to use deadly force to stop a dangerous suspect from escaping. Private citizens do not. If the person is running away and poses no immediate threat of serious harm to anyone, you cannot shoot — even if the underlying crime was serious. This is the single most common reason people who attempt citizen’s arrests end up charged themselves.
If the Person Fights Back
Indiana’s self-defense protections still apply if the person turns violent, and the state imposes no duty to retreat.3Indiana General Assembly. Indiana Code 35-41-3-2 – Use of Force to Protect Person or Property The legal framework shifts at that point from the arrest statute to self-defense, and a jury will look closely at whether your response was genuinely defensive or crossed into retaliation.
Shopkeeper’s Privilege Is a Separate Rule
Store owners and employees operate under a different statute, Indiana Code 35-33-6-2, not the general citizen’s arrest provision. If a store owner or agent has probable cause to believe a theft is happening or has happened, they can detain the suspect, ask for identification, verify it, check for unpurchased merchandise, and contact police.4Indiana General Assembly. Indiana Code 35-33-6-2
The detention has to be reasonable in both manner and length, and it cannot last longer than two hours or the arrival of a law enforcement officer, whichever comes first. If the suspect is under 18, the store cannot have them sign anything admitting the theft or waiving rights unless the minor has had the chance to consult a parent, guardian, or similar figure, and any statement obtained in violation of that rule is inadmissible against the minor.4Indiana General Assembly. Indiana Code 35-33-6-2
What Happens If the Arrest Was Unlawful
An arrest that doesn’t meet the statute doesn’t just fail — it exposes you to prosecution. The two most common charges are criminal confinement and battery.
Knowingly confining someone without consent is criminal confinement, a Level 6 felony at baseline under Indiana Code 35-42-3-3. The charge rises if a vehicle was involved, if the person was under 14 and not your child, or if any bodily injury occurred, which pushes it to a Level 5 felony. Moderate bodily injury makes it a Level 4, and a deadly weapon, serious bodily injury, or an aircraft makes it a Level 3.5Indiana General Assembly. Indiana Code 35-42-3-3 – Criminal Confinement A well-intentioned but legally unjustified detention that involves a struggle can land at Level 5 quickly.
Battery runs on a similar ladder. Any rude, insolent, or angry physical contact is a Class B misdemeanor; contact causing bodily injury is a Class A misdemeanor; moderate bodily injury is a Level 6 felony; serious bodily injury or a deadly weapon is a Level 5 felony.6Indiana General Assembly. Indiana Code 35-42-2-1 – Battery Restraining an unwilling person tends to produce injuries, and each one creates an additional charge if the arrest itself wasn’t justified.
Civil liability is the second layer. The person you held can sue for false imprisonment, assault, and battery. False imprisonment turns on confinement without legal authority and without consent, and if your arrest didn’t satisfy Indiana Code 35-33-1-4, you had neither. Damages can cover physical injuries, emotional distress, lost wages, and in serious cases punitive damages. Acting in good faith is not a defense when the statutory elements weren’t met.
Before You Act
The authority exists, but using it is genuinely risky. People most often get this wrong by acting on suspicion rather than knowledge. If you didn’t see the felony and don’t have concrete facts amounting to probable cause, you are betting your freedom on a judgment call that a prosecutor and jury will review with full hindsight.
If you witness what looks like a crime, call 911 first. Be a good witness: appearance, direction of travel, vehicle, plate. If someone poses an active danger and you decide to intervene physically, use the least force the moment requires and hand the person to police as soon as they arrive. Do not question them, search them, or move them somewhere else. Each of those steps adds legal exposure without adding anything useful to the eventual prosecution.
The statute gives you a right to act. It does not give you training, equipment, or the legal protections officers have. A citizen’s arrest fits a situation where lives are in danger and police are not yet there — not property crimes, neighborhood disputes, or anything that a phone call and a clear statement to a dispatcher would resolve just as well.
