The National Accountability Bureau (NAB) has issued directives at all national airports to notify the bureau if any of the 16 accuseds named in the Rental Power Projects (RPPs) case attempted to leave the country. The SC had ordered all 16 offenders in the case, including the prime minister, to be arrested, and gave a 24-hour deadline to the authorities to implement the orders. The court maintained that NAB will be responsible if any of the respondents managed to escape. NAB sources said the bureau had already written a letter to the Interior Ministry to place the name of the 16 offenders in the exit control list (ECL) and the request had been refreshed following SC orders for arrest of the 16 individuals involved in the RPPs case. Sources also said NAB had instructed immigration authorities at all national airports to stop any of the 16 offenders immediately if they attempted to leave the country, and inform the bureau.
