Aiding escape of state prisoners is criminalised, including rescuing or harbouring, punishable by long imprisonment and fine. Section 158 criminalises knowingly aiding, assisting, rescuing, attempting to rescue, harbouring, concealing or offering resistance to the recapture of a State prisoner or prisoner of war who escapes from lawful custody; conviction may attract imprisonment for life or imprisonment for a term which may extend to ten years, and a fine, and parolees exceeding permitted limits are treated as having escaped for these purposes.
