The definition of false imprisonment from the learned authors of Clerk and Lindsell on Torts, 14th Edition at page 681 is found quite apt in the resolution of this head of claim. The tort of false imprisonment is defined as follows:- “A false imprisonment is complete deprivation of liberty for anytime however short without lawful cause, imprisonment is no other thing but the restraint of a man’s liberty whether it be in the open field, or in the stocks or in the cage in the street, or in a man’s own house, as well as in the common goalie; and in all the places the party so restrained is said to be a prisoner so long as he hath not his liberty freely to go at all times to all places whither he will without bait or main praise or otherwise. The prisoner may be confined within a definite space by being put under lock and key or his movements may simply be constrained by the will of another”. The law will support a person who had good reasons to make a report to the police on an offence so long as he wants them to use their own discretion in taking further steps. An action for false imprisonment will not lie against an individual who merely gave information to the police, on their initiative to arrest a suspect. However a party to an action for false imprisonment may succeed, if he can prove that it was the other party that was actively responsible in setting the law in motion against him.
