Harbouring escaped offender: knowing concealment to prevent apprehension attracts graded imprisonment and fines under penal law. Knowingly harbouring or concealing a person who has escaped lawful custody or against whom a lawful order for apprehension exists, with intent to prevent apprehension, is an offence subject to graded punishments tied to the seriousness of the underlying offence: up to seven years and fine where the underlying offence is death penalty eligible; up to three years, with or without fine, where it is punishable with life or ten years' imprisonment; and up to one fourth of the maximum term (or fine or both) where the underlying offence is punishable with imprisonment not extending beyond ten years. Extraterritorial acts liable to extradition are included, and the spouse of the wanted person is exempted.
