Indian Penal Code, 1860
340. Wrongful confinement
Whoever wrongfully restrains any person in such a manner as to prevent that person from proceedings beyond certain circumscribing limits, is said "wrongfully to confine" that person.
(a) A causes Z to go within a walled space, and locks Z in. A is thus prevented from proceeding in any direction beyond the circumscribing line of wall. A wrongfully confines Z.
(b) A places men with firearms at the outlets of a building, and tells Z that they will fire at Z if Z attempts to leave the building. A wrongfully confines Z.
