The Federal Public Service Commission (FPSC) here on Friday withdrew the earlier notified names of the successful candidates who appeared in the Competitive Examination-2009 and qualified for the recruitment against BS-17 posts under the federal government, a private TV reported. The action was taken after some mistakes were pointed out in the result affecting the merit, which remained displayed at the official website of the commission for one day. The error occurred due to some computer glitch. Authorities concerned told that an internal enquiry has been initiated to look into the matter. FPSC IT chief said that on instructions of DG Exams and Secretary the result was offloaded from the web. 'I am not aware of the reasons behind the action.'
