The students reportedly paid various sums of money ranging from ₵1,500 to ₵4,000 to have their poor exam grades changed.
This fraud, according to reports was first detected by the Academic Affairs Director of the university.
He became suspicious of the grades of one of the average students in his class when he requested for a transcript.
The Academic Affairs Director reported the development to management and a was committee set to investigate the development.
An external auditor was subsequently contracted to investigate the fraud.
The investigations conducted by the AKK Risk Management Consult into the scandal, fingered Deputy Director of the ISTD, Paul Danquah in the fraud.
His password was apparently used to manipulate the grades.
Further investigations by the BNI into the scandal point to the involvement of a director of one of the departments, Edwin Ayernor.
A report released after the probe indicated that phone records of Edwin Ayernor showed that his services were solicited for the grade change.
Mr Ayernor however denies knowledge.
“The BNI took my computer, documents and my phone. They have returned all these items to me so the question is if the BNI found something incriminating me on the phone why will they return it to me,” he said.
Counsel for the university, Fortunate Fio told Joy News reporter investigations are still ongoing and the culprits will be duly punished.
He said the grades of the 22 students have been reversed.
“I can safely say that our students. They were supposed to have graduated last year and most of them had papers to write so the grade change actually occurred in relation to those papers and we have reversed them.” he said.
