Yes, within limits. A merchant who has probable cause to believe you are taking or have taken merchandise may hold you for a reasonable time to investigate, and in some situations store staff may make a private person’s arrest and then turn you over to police. The merchant statute also limits the force a store may use, what it may search, and what it may demand from you.

What the store needs before it can stop you

A merchant’s detention power applies only when the merchant has probable cause to believe you are attempting to unlawfully take, or have unlawfully taken, merchandise from the premises (Penal Code section 490.5(f)(1)). The detention may last “a reasonable time” and must be “for the purpose of conducting an investigation in a reasonable manner.” The statute does not set a fixed number of minutes. The permitted length depends on what a reasonable investigation needs, such as checking the item or reviewing footage, not on an open-ended hold.

Holding you until officers arrive can also rest on a separate power. Any private person, which includes a store employee, may arrest someone for a public offense committed or attempted in that person’s presence, among other grounds (Penal Code section 837), and the merchant statute itself refers to a “detention or arrest by a merchant” (Penal Code section 490.5(f)(7)). A private person who arrests someone must, without unnecessary delay, take that person before a magistrate or deliver them to a peace officer (Penal Code section 847(a)).

What physical contact the store can use

If a store employee grabs you, blocks your path, or otherwise physically restrains you, the law limits that contact too. In making the detention, a merchant may use “a reasonable amount of nondeadly force necessary to protect himself or herself and to prevent escape” of the person detained or the loss of property (Penal Code section 490.5(f)(2)). Force beyond what those purposes require, or force used to punish you, is not authorized by this statute.

While you are detained, the store may examine, for the purpose of figuring out ownership, any item it has probable cause to believe was unlawfully taken, as long as that item is in plain view (Penal Code section 490.5(f)(3)).

A search goes a step further, and the statute sets out the order (Penal Code section 490.5(f)(4)). First, the store may ask you to give up the item voluntarily. Only if you refuse may staff conduct “a limited and reasonable search” to recover it, covering “packages, shopping bags, handbags or other property in the immediate possession of the person detained” but not “any clothing worn by the person.” Once the item is surrendered or found, you “may also be requested, but may not be required,” to provide adequate proof of your identity.

If it turns out you were innocent

Being stopped, even being wrongly stopped, does not automatically make the store liable to you. In a civil lawsuit over a detention or arrest by a merchant, it is a defense that the merchant had probable cause to believe you had stolen or attempted to steal merchandise and acted reasonably under all the circumstances (Penal Code section 490.5(f)(7)). For that defense, the question is whether the store had probable cause and behaved reasonably at the time, not whether you turned out to be guilty.

What happens if police get involved later

The store’s authority under section 490.5 is separate from police arrest powers, and a store letting you leave does not stop police from investigating. Since January 1, 2025, officers who did not witness a shoplifting offense (Penal Code section 459.5) can still arrest for it without a warrant, but only with probable cause, an arrest made “without undue delay after the violation,” and at least one listed circumstance, such as an officer viewing video that shows you committing it or your confession to the arresting officer (Penal Code section 836(f)).

What to note if this happens to you

The specific facts of a detention often decide whether it stayed within these limits. Write down and gather these as soon as possible:

  • How long you were held, and what was said to you during that time.
  • Whether anyone touched, blocked, or restrained you, and how.
  • What, if anything, was searched, and whether you were asked, or told, to empty pockets, bags, or clothing.
  • Whether you were asked for identification, and what happened when you did or did not provide it.
  • Whether and when police were called, and how long officers took to arrive.
  • The names or descriptions of employees involved, and any witnesses.

If you were detained or charged

Whether a store stayed within these limits can matter to any shoplifting or theft case that follows, and to any claim you may have against the store. The Law Offices of David S.
