(3) In reckoning the period of forty-eight hours specified in sub-section (1), Sundays and other public holidays shall be excluded.

(4) Subject to the provisions of this Act, the Central Government may make rules providing for the manner in which and the period for which any person subject to this Act may be taken into and detained in Security Guard custody, pending the trial by any competent authority for any offence committed by him
