The Trespass Notice, the Open Car Door, and the 18-Minute Police ETA
At 02:15 you are on foot patrol in the surface lot of a 312-unit apartment complex in Kent County. Post orders are explicit: observe and report, no physical contact, do not enter occupied units without police. Six weeks ago a written no-trespass notice was served on a man named D.R. after repeated noise and vehicle complaints; the notice names D.R. and bans him from "the entire property, including all common areas, parking areas, and walkways." Under the lot lights you see D.R. leaning into the open passenger door of a car that is not his, removing a bag. He straightens, sees you, and says, "Relax, I'm here to see my girl in 214." The car's interior light is on and the door is open. He begins walking toward Building 2. Your radio check puts police 18 minutes out. Your supervisor is off shift and not answering. You are unarmed, with a radio, phone, and flashlight.
1. At the moment you recognize D.R., what legal footing do you actually have? Distinguish the trespass notice, citizen's arrest, and detention.

Keep the three concepts separate, because they authorize very different things.
The trespass notice supports a request to leave and, if refused, a report. A valid written notice naming the person and the property gives you a strong basis to tell D.R. he is not permitted on the property and that he must leave now. It does not, by itself, authorize you to grab him. Note the notice's scope: it covers parking areas and walkways, so his presence in the lot is covered - but if the notice had been limited to "Building 2," the analysis would change.
Citizen's arrest under Michigan's private-person arrest statute (MCL 764.16) is narrow: a felony committed in your presence, or a misdemeanor amounting to a breach of the peace committed in your presence. Entering an unlocked car is not automatically a felony in your observation, and you did not see him break anything. What you saw is suspicious, not yet chargeable as a felony in your presence.
Detention is not a free-standing power for private guards. You may ask questions and ask him to stay; you may not physically prevent him from leaving absent an arrest basis and a proportional use of force.
Say this plainly: the notice gives you authority to order him off the property and to report; it does not give you authority to seize him.
2. What do you do in the next 60 seconds? Give the sequence and justify each step.

Sequence matters more than the conclusion.
- Create and keep distance. Stop about 15–20 feet away, off his direct line to the building entrance, flashlight low and not in his eyes. You are alone and unarmed, and the most likely bad outcome is a fight you cannot win.
- Identify and state the order. "Security. You're on a no-trespass notice for this entire property. You need to leave now." Identification as a guard - not as police - is both an ethical duty and a legal safeguard.
- Give the specific reason once. "There's a notice dated last month with your name on it." Do not argue about his girlfriend.
- Radio in the description and direction of travel while keeping him in sight, and ask dispatch to relay to the responding officer that a vehicle may have been entered.
- Note the car. Record plate, make, model, and which door was open. Do not touch the car or the bag.
- Do not chase into the building. If he walks to the stairwell, stop at the entry, watch which floor, and report. Follow only within common areas you are authorized to patrol, and never into a unit.
The judgment being tested: your job is to interrupt, observe, and hand off a clean report to police - not to win the encounter.
3. D.R. ignores you, walks into Building 2 and goes up the interior stairwell toward unit 214. What are your limits, and what do you do?
Read the worked answer
Your authority thins out as he moves from the lot into the building and toward a private unit.
You may follow into common areas you are assigned to patrol - lobby, corridor, stairwell - while maintaining distance, because those areas are covered by the trespass notice and the property owner's authority. You may not force your way into unit 214, put a hand on the door, or demand entry. A residential unit is not your post. If the door is opened for him, stop at the threshold.
You may not physically pull him off the stairs. He has not committed a felony in your presence and has not committed a breach-of-peace misdemeanor that you observed; grabbing him now is an unlawful detention and a battery, and it hands him the better claim.
What to do: note the exact time he entered, which stairwell, which floor he stopped on, and which door he approached. Knock once, identify yourself, and ask the resident whether she is all right - do not push past her. Then wait for police in the lobby, complete an incident report noting the trespass notice date, the vehicle information, and the fact that police were requested at 02:16 with an 18-minute ETA. Notify the property manager in writing before the end of shift so the notice can be re-served or enforced by the owner through a civil action.
