KARACHI: The National Accountability Bureau (NAB) is investigating misuse of Green Channel facility, which caused a heavy loss to the national exchequer as well as enabled influx of various goods including contrabands into the country. Directorate of Risk Management Unit (RMU), Custom House, Karachi has forwarded the Green-Channel clearance data to National Accountability Bureau (NAB), Karachi as required by Director, NAB, Karachi Region. The NAB is in the process of analyzing the data and, as per a credible source, has demanded further data from Director (RMU) who was earlier reluctant to share the data on grounds that all data to be shared with NAB is required to be provided through the Office of Chief Collector. However, due to mounting pressure from the NAB, the data has been provided in first phase.
