The former immigration boss, David Parradang, has been quizzed by the Economic and Financial Crimes Commission (EFCC), for alleged corrupt practices.
The spokesperson for the EFCC, Wilson Uwujaren, confirmed to Channels Television that the former immigration boss was interrogated earlier on Monday.
Mr Parradang was suspended by President Buhari in August, weeks after a wanted terrorist, Alhmad Al-assir secured a Nigerian visa from Lebanon.
He is however, being quizzed for his alleged role in the 2014 immigration recruitment exercise during which applicants were made to pay a thousand Naira each.
It was alleged that the botched recruitment exercise yielded about 600 million Naira, but the immigration service declared 45 million Naira only.
Several job seekers died at different locations during the exercise that was canceled by the former President, Goodluck Jonathan.
Gov. Simon Lalong of Plateau, late August, met President Muhammadu Buhari to plead over the recent suspension of the Comptroller General of the Nigeria Immigration Service (NIS), Mr David Parradang.
Paradang, who was sighted in the Presidential Villa in company of the governor, after he was instructed to proceed on suspension.
Lalong, who briefed State House correspondents after a closed door meeting with Buhari, said that although investigations into the issues that led to the suspension of the Immigration boss had commenced, it was necessary for him to show concern.
“I came to see the President on some issues affecting my state.
“These include the prevailing issue of the suspension of the comptroller of general of immigration who incidentally is from my state. When you have issues like this in a political period, you must find ways of looking for reasons and possible solution.
“If anything affects any part of your body you must show concern.
“Paradang’s case is still under investigation. A man was suspended and he is from Plateau, it is my concern because I am the governor of the state.
“For every appointment, we must show concern no matter how small. The President is handling it.
“At the end of the day whatever is the outcome I will agree with it, but I also need to get some explanation as the governor of the state.
“I feel comfortable with the response I got and that is why I am smiling. I told him what we are doing on insecurity in our state.’’
