How to Arrest Someone

Arresting a Suspect as a Police Officer

Confirm you have reason to arrest. Legally, you can only make an arrest in a limited number of circumstances. For example, you can arrest someone in the following situations: You have an arrest warrant signed by a judge. You observed a crime being committed. You have probable cause to believe the suspect has committed a crime. To find probable cause, you must have specific facts and not a hunch that the person has committed a crime.

Immobilize the suspect. To make the arrest easier, you need to stop the suspect’s movements. You can use many different methods, such as verbal commands or Tasers. Your police force should have a “use of force” policy that lays out what force you can use and when. Know this policy by heart. If you don’t follow it, you can be sued for excessive use of force. Typically, the manual will explain a continuum of force. For example, you can start by issuing a verbal command: “Let me see your ID” or “Stop.” If the suspect doesn’t comply, you can use empty hand controls such as grabs or holds. The officer can increase the force up the continuum until the suspect complies. The final point on the continuum is deadly force. Your manual will explain the situations in which deadly force is appropriate. Use of force is so important you should receive training on it before being allowed into the field. Ask a supervisor if you have questions.

Gain control of the suspect. Once you immobilize the suspect, you need to control them. If you don’t, then you can injure yourself as you try to get the cuffs on. If necessary, you may need to move up the use of force continuum until you get sufficient control. Be alert for the suspect to attempt to break free at any point before they are handcuffed.

Handcuff the suspect. You should handcuff someone behind their back. If you handcuff in the front, they have too much freedom to move and may reach for a weapon or hurt you. Always cuff in back. Always place the backs of the hands together. This prevents suspects from sliding their hands down to the feet. After cuffing, make sure the handcuffs aren’t too tight. Also confirm they are secure.

Search the suspect. After cuffing the suspect, you should search them. Search for a weapon or other evidence of a crime. You can never be too careful. Search everyone, regardless of their gender, age, size, or race. Even very young and very old suspects have killed police officers. You might not be able to conduct your search immediately after arrest. For example, weather conditions might prevent a safe search. Also, you might have arrested someone with a mob of people around you. Move the suspect to a secure location before searching. Check the waist and groin areas first. A weapon is most likely stored there. Also be sure to conduct a second, more thorough search. If necessary, ask another officer to search the suspect as well.

Transport the suspect. Remain vigilant during the transport. You might relax, thinking everything is under control because the cuffed suspect is in the backseat. However, the suspect’s anxiety will increase the closer you get to your destination. Accordingly, you should be prepared for erratic or irrational behavior when you near the end of the transport. Remember to search the subject each time you transfer them to another officer or drop them off at a location. You might have overlooked a weapon, or the suspect could have obtained one during transport.

Give Miranda warnings if you want to ask questions. Once a suspect is in custody, you can’t interrogate them without giving Miranda warnings. If you don't give the warnings, then the prosecutor can't use the suspect's statements in court. There are four warnings: The suspect has the right to remain silent. Any statement the suspect makes can and will be used against them in court. They have the right to an attorney. If the suspect can’t afford an attorney, one will be provided to them.

Making a Citizen’s Arrest

Identify if you have reason to make an arrest. In some countries, private citizens can make arrests even if they are not sworn police officers. However, you can only make arrests in certain limited situations, which vary by location: You suspect the person has committed a felony, such as murder, rape, burglary, etc. However, your suspicion must be reasonable. Furthermore, the felony must actually have been committed. If it didn’t, you can be legally liable for the arrest. In Canada, and in some U.S. states, you must have actually observed the violent crime being committed before you can make a citizen’s arrest. Someone is breaching the peace. In many U.S. states, you can make a citizen’s arrest if you personally witnessed someone breaching the peace. For example, someone breaches the peace by fighting or making a loud disturbance.

Consider the risks. You shouldn’t attempt a citizen’s arrest without consider the risks and consequences. For example, quickly analyze the following: Does the suspect have a gun, knife, or other weapon? You don’t want to jeopardize your own safety or the safety of those around you by attempting an arrest. Is there a police officer nearby, or can you quickly call one? It is better to involve trained police. If possible, you can focus on getting a detailed, accurate description of the suspect instead of attempting an arrest. Can you quickly turn over the suspect to the police? If not, then don’t make an arrest. Do you know whether the suspect committed a felony? What qualifies as a felony differs depending on the state or country. If you're unsure, simply report the suspicious conduct to the police.

State you are making a citizen’s arrest. You’ll need to give an explicit warning that you are arresting the person. Shout, “Stop! I’m making a citizen’s arrest!” This will give the suspect a chance to turn themselves over. Also give the suspect a reason why you are arresting them. For example, "You're breaching the peace by fighting" is a sufficient reason.

Use reasonable force to subdue the person. You cannot use excessive force in order to make an arrest. Instead, use only the amount of force necessary to subdue the suspect. For example, if the person struggles only briefly, you can’t give him a left hook that knocks him out cold. A suspect might be desperate to avoid arrest. If so, they could put up quite a fight. Always remember to protect your own safety. If the arrest turns into a brawl, you should let the suspect go.

Call the police. As soon as possible, either call the police or ask another bystander to call the police. Don’t delay, since the arrested might become agitated. Ask the suspect to cooperate. Say, “Will you calm down? The police are coming. You don’t want to make any more trouble.”

Avoid questioning or searching the suspect. In the United States, a citizen’s arrest is not subject to the same Constitutional requirements as a police officer’s arrest. Accordingly, you aren’t prohibited from asking questions or searching the suspect. However, you probably should avoid doing so. Leave it to the police when they arrive. If you make an arrest at the request of the police, then your arrest is subject to the Constitution’s restraints. However, suspects can blurt out incriminating information. For example, a suspect might shout, “I didn’t know the gun was loaded!” Don’t follow up with questions, but you can give the police this information.

Tell the officer what happened. When the police arrive, give the facts of the incident. Be as accurate as possible and answer any questions about why you suspected the person of committing a crime. Also discuss what you did and said to arrest the person.
