Louisiana arrest laws require an officer to have probable cause before taking you into custody, bind that officer to specific procedures during and after the arrest, and guarantee you a court appearance within 72 hours. The rules come from the Louisiana Code of Criminal Procedure and the state constitution, with federal protections layered on top. What follows is what actually happens when those rules meet an arrest, and where you have leverage.
When Police Can Arrest You
Every lawful arrest begins with probable cause: enough factual evidence for a reasonable belief that a specific person committed a specific crime. A hunch or an anonymous tip, by itself, is not enough.
When officers have time, they go to a magistrate. The judge reviews the evidence under oath and signs an arrest warrant only after finding probable cause that the offense happened and that the named person committed it.1Justia. Louisiana Code of Criminal Procedure Art. 202 – Warrant of Arrest Issuance
Most street arrests skip that step. Louisiana allows a peace officer to arrest without a warrant in four situations:
- The offense is committed in the officer’s presence. For misdemeanors, the arrest must happen immediately or during close pursuit.
- The officer has information that the person committed a felony, even if the officer did not witness it.
- The officer has reasonable cause to believe the person committed any offense.
- The officer has reliable information that another Louisiana officer holds a warrant, or that an out-of-state or federal officer holds a felony warrant.
An officer in close pursuit under any of those circumstances can cross into another Louisiana jurisdiction to complete the arrest.2Justia. Louisiana Code of Criminal Procedure Art. 213 – Arrest by Officer Without Warrant When Lawful
An arrest, legally, is the moment one person takes another into custody through actual physical restraint or voluntary submission.3Justia. Louisiana Code of Criminal Procedure Art. 201 – Arrest Defined From that moment, the clock starts and specific rules bind the officer.
What Happens at the Moment of Arrest
What the Officer Has to Tell You
When making a warrantless arrest, the officer must tell you three things: that they intend to arrest you, what authority they have, and the reason for the arrest. The officer can skip this if you are actively committing the crime, fleeing, resisting, or if giving the information would jeopardize the arrest.4Justia. Louisiana Code of Criminal Procedure Art. 218 – Method of Arrest Without Warrant
Use of Force
You are required to submit peacefully to a lawful arrest. The officer may use reasonable force to carry it out and to overcome any resistance.5Justia. Louisiana Code of Criminal Procedure Art. 220 – Force in Making Arrest Reasonable is the operative word. Force beyond what the situation demands can support a civil rights claim or a defense motion later.
Booking
After the arrest, the officer has to promptly bring you to the nearest jail or police station for booking. The record includes your name and address, a list of any property taken from you, and the date and time.6Justia. Louisiana Code of Criminal Procedure Art. 228 – Booking of Arrested Person Submission of Booking Information Summary Most facilities also take fingerprints and photographs during intake.
Your Cell Phone
Pockets, wallet, and the area within your immediate reach can be searched when you are arrested. Your phone is treated differently. In Riley v. California, the U.S. Supreme Court held that officers generally need a warrant before searching the digital contents of a phone seized during an arrest.7Justia. Riley v. California, 573 U.S. 373 A phone holds more private information than almost anything else a person carries, and warrantless searches of it can be challenged unless an emergency exception applies.
The 72-Hour Rule and Bail
You do not sit indefinitely after an arrest. Louisiana requires that the officer or sheriff bring you before a judge within 72 hours, not counting weekends and legal holidays. At that hearing, the court appoints counsel if you qualify and may set or review bail.8Louisiana State Legislature. Louisiana Code of Criminal Procedure Art. 230.1 If the 72 hours pass without that appearance, your attorney can move to challenge your continued detention.
Bail is security posted to guarantee your appearance in court.9Louisiana State Legislature. Louisiana Code of Criminal Procedure Art. 311 Louisiana permits several forms, including commercial surety bonds, personal sureties who pledge their own property, and bonds executed electronically. The amount reflects the alleged offense, your criminal history, and whether the court sees you as a flight risk. A bail bondsman typically charges a non-refundable premium of roughly 6% to 10% of the bail amount.
Your Rights While in Custody
Searches
The Fourth Amendment protects you from unreasonable searches and seizures, and Article I, Section 5 of the Louisiana Constitution adds its own protection, securing every person against unreasonable searches, seizures, and invasions of privacy, and barring warrants that lack probable cause, oath, and a specific description of the place and items.10Louisiana State Senate. Louisiana Constitution of 1974 Louisiana courts have historically read this provision to give broader privacy protection than the federal Fourth Amendment. Anyone harmed by an illegal search has standing to challenge it.
The Right to Remain Silent
Before interrogating you in custody, officers must warn you of the right to remain silent, that anything you say can be used against you, that you have the right to an attorney, and that one will be appointed if you cannot afford one.11Constitution Annotated. Miranda Requirements These warnings come from Miranda v. Arizona. Statements made during interrogation without proper warnings can be excluded at trial. Statements you volunteer on your own, without being questioned, can still come in. That is why defense attorneys consistently tell clients to say nothing until a lawyer is present.
The Right to an Attorney
The Sixth Amendment guarantees counsel at the critical stages of a criminal case. If you cannot afford a private attorney, Louisiana’s public defender system, run by the Louisiana Public Defender Board within the governor’s office, provides one at no cost in every court in the state.12Justia. Louisiana Code RS 15-146 – Louisiana Public Defender Board Eligibility turns on income against the federal poverty guidelines. Courts set their own thresholds, often between 125% and 200% of the poverty level, which for a single person in 2026 starts from a baseline of $15,960 per year.13U.S. Department of Health and Human Services. 2026 Poverty Guidelines
Defenses That Can Undo the Case
Suppressing Illegally Obtained Evidence
When police violate your rights during an arrest or investigation, your attorney can move to suppress the tainted evidence. Common grounds include an arrest without probable cause, an illegal search, and the absence of proper Miranda warnings before interrogation. A successful suppression motion removes the excluded evidence from the prosecution’s case, and that loss alone can force a dismissal or a favorable plea. The details of the arrest matter most here: even a technically valid stop can unravel if the officer cut corners on a search or failed to document the basis for probable cause.
Self-Defense
Louisiana recognizes the right to use reasonable force to prevent a violent crime against yourself or to protect your property, and the force used must be proportional to the threat. Louisiana is a stand-your-ground state: if you are somewhere you have a right to be and are not engaged in illegal activity, you have no duty to retreat before using force in self-defense.14Louisiana State Legislature. Louisiana Code RS 14-19 – Use of Force or Violence in Defense Deadly force is justifiable only against a threat of death or serious bodily harm. The facts at the moment of the encounter usually decide these cases.
Entrapment
Entrapment applies when law enforcement induces you to commit a crime you would not otherwise have committed. The question is whether police went past providing an opportunity and actively pressured or manipulated you into the offense. If you were already predisposed and police just gave you the chance, the defense will fail. Prosecutors typically counter with evidence of predisposition, such as prior similar conduct or communications showing intent before any police involvement.
Clearing an Arrest Record Later
Louisiana lets people petition to expunge certain arrest and conviction records, which can matter for employment, housing, and licensing. The rules depend on how the case ended:
- Arrests without prosecution: if the time limit for prosecution has run and no charges were filed, the arrest record can be expunged. The same applies if charges were filed and later dismissed, or you were acquitted.
- Misdemeanor convictions: eligible for petition if at least five years have passed since you completed your sentence, probation, or parole. Sexual offenses and domestic violence convictions are not eligible. One misdemeanor expungement is allowed per five-year period; DWI convictions are limited to one expungement per ten years.
- Felony arrests without conviction: available where the district attorney declined to prosecute, the charges were dismissed, or you were acquitted. The court also weighs whether the arrest record has value as evidence in any future prosecution.
- Certain felony convictions: limited expungement is available for convictions dismissed under deferred sentencing provisions and for specific nonviolent first offenses, with a hearing involving the district attorney and the arresting agency.
DWI arrests are carved out from the standard rules. First and second DWI offenses that did not result in prosecution cannot be expunged under the general arrest-record provision.15Justia. Louisiana Code RS 44-9 – Records of Arrests Filing fees vary by parish, so check with the clerk of court where the arrest or conviction occurred before you file.
