Senator Dino Melaye, of Kogi West has been accused of not graduating from Ahmadu Bello University (ABU), Zaria.
Lecturers from the university claim that Melaye bribed his Head of Department who assisted him to forge his transcript and that his name was not on the graduation list.
These revelations were made in a series of tweets by Sahara Reporters.
The tweets claim that the Department of State Services (DSS) was informed of this but that the security agency covered it up.
However, Senator Melaye has denied the allegations and dared Sahara Reporters to sue him and ABU if it had authentic evidence to back its claims.
Some Nigerians believe Melaye is being witch hunted by the government for his strong opposition of the Buhari administration on certain issues and have called on the senator to shame the government by providing proof that he indeed graduated.
Meanwhile, former Majority Leader of the Senate, Senator Ali Ndume, has called on the upper chamber of the National Assembly to investigate the certificate scandal involving Senator Dino Melaye.
Dino Melaye has expressed his willingness to submit himself for investigation saying it was imperative for him to clear himself of the scandal as a Senator of the Federal Republic of Nigeria.
Melaye said he was optimistic that the Senate Committee on Ethics and Privileges would clear him of the allegations.
