NRS § 171.104 - Definition of "Arrest" in Nevada Law

What is an arrest in Nevada? (explained by Las Vegas criminal defense lawyers)

Watch this video on YouTube

Under NRS § 171.104, Nevada law defines an arrest as “the taking of a person into custody, in a case and in the manner authorized by law. An arrest may be made by a peace officer or by a private person.”

Arrests are often the first stage in the Nevada criminal process. Whenever police arrest suspects pursuant to NRS 171.104, the police are required to read them their “Miranda warnings” prior to interrogating them.

Police usually ask judges to issue an arrest warrant before they apprehend suspects. But warrants are not required to take suspects into custody as long as the police have “probable cause” to believe they committed a crime.

An arrest pursuant to NRS 171.104 must be based on probable cause for it to be lawful.

1. Definition

NRS 171.104 defines an arrest as “the taking of a person into custody, in a case and in the manner authorized by law.”¹ Nevada police may arrest people when they have “probable cause” to believe they committed a crime.²

In the typical arrest situation, police officers verbally inform suspects they are under arrest. Then police place them in handcuffs and transfer them to the police station for booking, mug shots, and fingerprints. Suspects remain in law enforcement custody pending how the criminal case proceeds.

Most arrestees are eligible to be released on bail or own recognizance release. Arrestees who get released are given a court date to return for their arraignment (the formal reading of the criminal charges).

2. Arrest versus detention

An arrest under NRS 171.104 is when the police take criminal suspects into custody. By contrast, detention is when police temporarily detain criminal suspects in order to determine whether to arrest them.

Police are legally allowed to temporarily detain people they “reasonably” believe may have committed a crime or civil infraction. This “reasonable belief” standard police need to detain a suspect is lower than the “probable cause” standard police need to arrest a suspect.

During a detention, the detainees are required to identify themselves. However, they are not required to answer any other questions. If the police reasonably believe detainees are armed or are safety threats, the police may search them to the extent necessary to discover and seize any weapons.

These detentions must be a short as possible, and in no event more than an hour. Detentions must take place in the location where the police encountered the suspects; police may not transport detainees for just a detention.

If during a detention the police gain probable cause to believe the detainee committed a crime, the police can execute an arrest. But if the detention does not lead to probable cause, then the police must release the detainee.³

3. Timing and execution

People suspected of committing a felony or gross misdemeanor may be arrested at any time of day.

Meanwhile, people suspected of committing a misdemeanor may be arrested only between 7:00 A.M. and 7:00 P.M. unless either of the following situations occur:

the magistrate judge directed otherwise;
the suspect allegedly committed the misdemeanor in the arresting officer’s presence;
the suspect allegedly committed the misdemeanor in the presence of a private citizen, who immediately conducted a citizen’s arrest (go to section 6 for more information);
the suspect allegedly violated a restraining order (NRS 33.350) against domestic violence;
the suspect is already in custody as a result of another lawful arrest;
the suspect voluntarily surrenders in response to an outstanding arrest warrant;
the suspect allegedly committed battery domestic violence (NRS 200.485) within the last 24 hours; or
the suspect is found in public, the arrest is made in public, there is an arrest warrant, and the police discovered the misdemeanor because they had probable cause to stop, detain, or arrest the suspect for another alleged offense⁴

If the police have reasonable grounds to believe the suspect is hiding in a particular location, the police must first demand that they be let in and explain the reason. Only then may the police lawfully break open a door or window to get inside.

An officer may use deadly force to arrest a person only if:

it is necessary to prevent escape; and
the police gave a warning (if feasible); and
there is probable cause to believe the suspect poses a threat of serious bodily harm or committed a felony which involves serious bodily harm or the use of deadly force

And if the suspect has any dangerous weapons on his/her person, the arresting officer may seize them.⁵

4. Custodial interrogation and Miranda

Police are required to read arrestees their rights — called Miranda warnings — before they are placed in “custodial interrogation.” As it sounds, custodial interrogation has two elements:

the arrestee is in police custody (and therefore not free to leave), and
the police are asking questions of (“interrogating”) the arrestee

Therefore, police do not have to read arrestees their Miranda rights until they begin asking them questions. Depending on the situation, the interrogation can occur several hours or longer after the physical arrest.

Miranda warnings inform arrestees of their Fifth Amendment right against self-incrimination and their Sixth Amendment right to an attorney. Specifically, police read arrestees the following:

“You have the right to remain silent. Anything you say can and will be used against you in a court of law. You have the right to speak to an attorney, and to have an attorney present during any questioning. If you cannot afford a lawyer, one will be provided for you at government expense.”⁶

5. Arrest warrants versus warrantless arrests

A warrant is not necessary to apprehend someone if there is probable cause that the suspect committed a crime.

Police need a current and valid arrest warrant in order to arrest a person in Nevada unless they have probable cause to believe the suspect committed a crime.

Note that if a person gets arrested without probable cause, the illegal arrest may be sufficient grounds to get any ensuing criminal charges dismissed.

5.1. Arrest warrants

When police believe a person may have committed a crime, the police typically compose an affidavit (called an “information”) explaining why there is probable cause to suspect the person. Then the police go to court and ask the judge to issue an arrest warrant.

If the judge agrees that there is probable cause, the court will issue the warrant. At that point, the police are free to seek out the suspect to arrest him/her pursuant to NRS 171.104.

(In rare cases, an arrest warrant is issued following an “indictment” rather than an “information.” An indictment is when a grand jury determines whether sufficient evidence exists to arrest a suspect of a crime.)

As long as an arrest warrant is outstanding, the person named in the warrant is vulnerable to arrest. Even if the person is pulled over for a minor traffic offense, traffic officers can arrest the person once they run the person’s name and see there is an outstanding warrant.⁷

5.2. Warrantless arrests

Sometimes there is no time to go to a judge and get an arrest warrant before apprehending a criminal suspect. This frequently happens when the alleged crime just occurred or is about to occur, or if the suspect is fleeing the scene.

Police may execute a warrantless arrest in either of the following circumstances:

The suspect committed any crime in the presence of the officer;
The suspect committed a gross misdemeanor or felony (whether or not the officer was present); or
A felony or gross misdemeanor has been committed, and the officer has probable cause to believe that the suspect committed it ⁸

6. Citizen’s arrests

A citizen’s arrest under NRS 171.126 is when a person who is not a peace officer places another person under arrest. Citizen’s arrests are much rarer than arrests by law enforcement, but they are perfectly legal under either of the following three circumstances:

the suspect committed any crime in the private citizen’s presence;
the suspect committed a felony whether or not in the private citizen’s presence; or
a felony has been committed, and the private citizen has “reasonable cause” for believing the suspect committed the felony⁹

Rosky v. State, 121 Nev. 184, 111 P.3d 690 (2005)(“The Fifth Amendment privilege against self-incrimination provides that a suspect’s statements made during custodial interrogation are inadmissible at trial unless the police first provide a Miranda warning.” “Custody” for Miranda purposes means a formal arrest or restraint on freedom of movement of the degree associated with a formal arrest. If there is no formal arrest, the pertinent inquiry is whether a reasonable person in the suspect’s position would feel “at liberty to terminate the interrogation and leave.” A court must answer this question by taking an objective look at “all of the circumstances surrounding the interrogation.” The United States Supreme Court has recently indicated that a suspect’s prior history with law enforcement has no bearing on the objective determination of whether the suspect is in custody for Miranda purposes, although this factor may be relevant in deciding whether a confession is voluntary.”).
