What Is a Citizen's Arrest? What Security Guards and Business Owners in California Need to Know

If you work in security or run a business in California that hires security, you've probably heard the term "citizen's arrest" - but what does it actually mean, and when can you legally perform one in California?

The law for citizen’s arrest varies by state, so understanding California’s specific case is crucial to know for anyone responsible for the safety of a business, venue, or event. Getting it wrong or making a mistake can expose you to serious legal liability.

Here's what you need to know.

Is a Citizen's Arrest Legal in California?

Yes it is, but with very important limitations.

California Penal Code § 837 says when a private citizen can make an arrest when:

• A public offense is committed or attempted in their presence
• The person arrested has committed a felony, even if not in their presence
• A felony has in fact been committed and the arresting person has reasonable cause to believe the person arrested committed it

The key word throughout is presence. For misdemeanors, you generally must have directly witnessed the offense. For felonies, the law gives more flexibility - but you still must have reasonable cause and the felony must have actually occurred.

What Changed in California After 2021?

California significantly reformed its citizen's arrest laws in 2021 following some high-profile incidents across the country. The reforms decreased the circumstances where a private person can perform an arrest and strengthened protections against wrongful detention.

California now takes a more restrictive approach than many other states. If you detain someone incorrectly, you can face civil liability for false imprisonment or even criminal charges.

What Does This Mean for Security Guards?

Security guards in California operate as private citizens under the law - they do not have special arrest powers beyond what any member of the public has.

This is one of the most important things to understand about working in private security.

What security guards can do:

• Detain someone they directly witness committing a crime on the property they are employed at
• Use reasonable, proportionate force to prevent someone from leaving until police arrive
• Document the incident and cooperate fully with law enforcement when they arrive

What security guards cannot do:

• Arrest someone based solely on suspicion without witnessing the offense
• Use excessive force during a detention
• Conduct searches without consent

This is why the proper training is so important. A security guard who overdoes it can put themselves - and their employer - at serious legal risk if performed outside of the legal guidelines.

What Does This Mean for Business Owners?

If you own a bar, nightclub, retail store, or event venue in Sacramento, your staff and security personnel are held to the same rules. If a guard makes an illegal detention on your property, the business owner can be held liable.

The safest approach:

• Train your staff on exactly what they can and cannot do when performing a citizen’s arrest
• Always call law enforcement rather than handling situations independently
• Work with professional, licensed security personnel who understand California law and citizen’s arrest thoroughly

When Should You Call the Police Instead?

You should always call the police first before inserting yourself into the situation. Citizen's arrest is a last resort, not a first response.

Unless you are directly witnessing a crime in progress and law enforcement cannot respond in time, it is almost always safer and smarter to be a witness and let trained officers handle the situation.

Professional security guards are trained to de-escalate, observe, document, and contact law enforcement - not to act as substitute police officers.

This is exactly the approach we take at Securing Communities. We teach all of our security officers the exact letter of the law, so they are prepared for any scenario that might appear when on the job.
