The Economic and Financial Crimes Commission (EFCC) has detained King Turner, a close associate of former President Goodluck Jonathan, over N240 million Universal Basic Education Commission (UBEC) contracts.
The suspect was flown to Lagos last night from Abuja for another round of grilling in respect of a separate case.
It was learnt that he will be returned to Abuja later on Wednesday.
Turner is a former chairman of the Board of UBEC when the alleged N20billion fraud was perpetrated.
A former UBEC Executive Secretary, Mallam Suleiman Dikko and a principal officer of the House of Representatives, have been quizzed by the anti-graft agency in connection with alleged N20 billion fraud at the commission.
The N20billion was allegedly siphoned through the purchase of science and technical equipment and MDGs’ books for some 104 Unity Schools between September 2012 and 2014.
EFCC detectives are believed to have been told by the principals of the “beneficiary” schools that they never got the books and equipment listed against their schools.
The EFCC is working on clues that part of the funds may have been diverted to the prosecution of 2015 general elections.
Turner was arrested before the Easter holidays and detained for interrogation.
