A false arrest is the unreasonable seizure of someone's personality. A seizure is considered unreasonable when there is a lack of probable cause to support it.Making a false arrest is a type of police misconduct. Police who engage in misconduct should be held accountable. In the US, a "false arrest" requires that a LEO KNOWINGLY arrests a person against whom they do not have probable cause. False arrest is a crime that causes harm to an innocent party who can sue for damages in a civil lawsuit. Falsely arrested means arrested without legal justification. Mere arrest is seldom grounds for a law suit. In that case, one individual holds another against their will or takes them into custody without consent or legal authority to do so. A police officer commits false arrest if they take into custody or otherwise detain another person without consent or legal justification.
