(2)An immunity granted to a person under sub-section (1) may, at any time, be withdrawn by the Central Government, if it is satisfied that such person had, in the course of the proceedings, not complied with the condition on which the immunity was granted or had given false evidence, and thereupon such person may be tried for the offence with respect to which the immunity was granted or for any other offence of which he appears to have been guilty in connection with the contravention and shall also become liable to the imposition of any penalty under this Act to which such person would have been liable, had not such immunity been granted.
