ISLAMABAD  – National Accountability Bureau (NAB) has decided to go tough against the sharif family after their refusal to appear before the NAB.

NAB is mulling to take unilateral action against former prime minister Nawaz Sharif if he continues to remain absent, revealed the NAB sources.

It has been learnt that the non-appearance of ousted premier and his sons is also a contempt of court.

NAB has clarified that the notices were received by the security staff of Sharif family, and it has documented proofs of that.
