Former Special Prosecutor has levelled allegations regarding corruption, payroll fraud, and unlawful recruitment practices within the Office of the Special Prosecutor (OSP).

At the heart of his allegations is an alleged failure to properly vet employees, instead subjecting them to unlawful polygraph tests, a practice which Amidu insists is illegal under Ghanaian law. "The OSP employees who contacted me are ready, able, and willing to speak at an impartial investigation that they were never vetted by the Ghana Police Administration, and the National Intelligence Bureau (NIB). "The OSP employees assumed that the Special Prosecutor, William Kissi Agyebeng's, unlawful polygraphing them could pass for vetting under Regulation 7 of the Office of the Special Prosecutor Regulations, 2018 (LI 2373) for purposes of their probation and confirmation of appointment under Regulation 12 thereof. "The first OSP employee to contact me after I had explained the processes of vetting employees of the OSP, stated that: "I am absolutely shocked to my boots by your latest revelation!" When I asked my interlocutor: "Which of the revelations? "If the police and NIB vetted, you would have known.

The police take your fingerprints etc to ensure you are not an ex-convict, and NIB would have done the deep vetting of all schools and certificates on your CV," the answer was: "I mean the colossal breaches!

This employee admitted he was polygraphed, not vetted," he said in a statement on December 26, 2025.
