The Shoplifting Detention That Went Wrong
You are a uniformed guard at a 24-hour grocery store. At 22:40 the manager points out a man in a bulky coat who she says put two bottles of spirits into an inner pocket. You have no direct view of the concealment. The man walks past all registers and out the door. You follow, identify yourself as security, and say "Stop, you're under arrest for theft." He keeps walking toward the parking lot. You grab his sleeve; he pulls away, drops a bottle that shatters, and shouts "Get off me." A bystander begins filming. Your post orders say guards may detain for theft but must call police immediately and may use only the force necessary. The store has a policy against pursuing suspects beyond the sidewalk.
1. Did you have lawful grounds to detain, and what is the strongest legal risk in how you acted?

The detention rests on the manager's report, not your own observation. A citizen's arrest generally requires that a felony was in fact committed (or, in some jurisdictions, a reasonable belief) and that the person is promptly handed to police; shopkeeper's privilege statutes vary widely on whether the guard must personally witness the concealment. The manager's account may be enough for reasonable suspicion to approach and investigate, but "you're under arrest" is a stronger claim than the facts you personally hold. The bigger risk is the physical grab after he ignored a verbal command. Even where a detention is lawful, force must be proportionate and used only to overcome resistance. Grabbing clothing is a low-level physical intervention, but if it escalates and he is injured, you must justify each step. Document exactly what the manager saw, what you saw, the words used, and the timing of the police call.
2. He has now dropped the bottle and is still walking. What should you do next, and why?

Stop the physical contact and step back. The suspected theft of two bottles does not justify a wrestling match in a parking lot, and the store policy bars pursuit past the sidewalk. Continuing to grab a person who is actively pulling away turns a property offense into a potential assault and injury claim against you and the employer. Instead: note his direction of travel and clothing, keep a safe distance, call police with a description and the manager as a witness, preserve the shattered bottle and any CCTV, and ask the bystander to remain. If he returns or becomes a threat to others, reassess. The proportionate response is to let him go and hand the evidence to police, not to win the physical contest.
