CBI nets Chidambaram, who's next?

Ever since former Union Finance Minister P Chidambaram was arrested by the CBI on late Wednesday in connection with INX Media case and his subsequent remand of five days, the Congress leaders and others have hit out against the Modi govt accusing it of witch-hunting. Meanwhile, the BJP leaders have defended the govt stating that it's a mere crackdown on corruption.

So, is it crackdown on corruption or selective targeting of opposition leaders? And if yes, then, who is next?
