Former premier Najib Abdul Razak's family can turn to the courts if they believe the authorities were wrong in freezing their bank accounts, said former premier Dr Mahathir Mohamad.<br /><br />“If they say it is wrong, they can take it to court,” he told a press conference in Putrajaya today.<br /><br />Mahathir also denied that his administration was taking revenge against Najib and claimed that he never complained when the previous government took similar action against his friends.
