The second great class of trespasses against the person consists of cases of false imprisonment.87

False imprisonment is any unlawful detention of any person.

In an action for damages for false imprisonment the motives of the defendant are not material, except in mitigation of damages. In McConnell vs. Kennedy88 the court said: "In such an action it does not seem to us that the motive with which the prosecution is instituted constitutes any element of the cause of action. If a prosecution is commenced against a party and he is arrested without lawful authority, the person who procures such arrest, no matter how pure or laudable may have been the motives of the prosecutor in instituting the prosecution, may be liable to an action for false imprisonment, because he caused a citizen to be sailed because of the unlawfulness of the first assault, and the assailant because of the excess of the force used by the other in defending against the original assault." Street's Foundation of Legal Liability, Vol. I, p. 7. Dole vs. Erskine, 35 N. H., 603; Gratton vs. Glidden, 84 Me., 589; Slone vs. Slone, 2 Met. (Ky.), 339. 87 "Forcefully to deprive a man of the freedom to go whithersoever he may is clearly a trespass. False imprisonment was indeed one of the first trespasses recognized by the Common law (Bracton's Note Book II, p. 314 (1229), pl. 465). A laying of violent hands upon the person and an actual forceful deprivation of liberty is the element undoubtedly at the root of liability in this wrong. In other words, the typical original imprisonment involved a battery. But the wrong was not destined to be restricted to such narrow bounds. Just as the assault represents an extension of the conception of harm involved in the battery in one direction, so the wrong of imprisonment represents the extension of that conception in another direction. Accordingly it has been settled that actual physical constraint or physical contact is not necessary to make an imprisonment. Coercion of any kind, as where the person yields without resistance to superior force or to authority, is enough. But some form of coercion is essential. One who is prevailed upon by false representations to go and remain at a particular place is not imprisoned, unless, perchance, force or intimidation be used to prevent departure."
