Economic and Financial Crimes Commission (EFCC) has detained the Comptroller of Prisons in charge of Nigeria Prisons Service Training School in Kaduna, David Haniel, over an alleged N50 million scam.

The alleged scam borders on 'obtaining under false pretence' and issuance of dud cheques to some Nigerians.

This is coming just as it was reported that the EFCC also interrogated Speaker of the Ogun State House of Assembly, Tunji Egbetokun, on Wednesday over an alleged N30 billion fraud in the state.

Haniel, arrested since June 28, is alleged to be a specialist in using his official position to dupe contractors and food suppliers to prison inmates.

It was also gathered that one of such victims is the owner of Vicki Nwodu Nig Enterprises, a supplier of foodstuff to prison inmates while Haniel was Comptroller of Prisons in Adamawa in 2005.

The contractor supplied the foodstuff but was eventually duped allegedly by the comptroller of N2 million.

Nemesis caught up with him when in 2008 as the Commandant of the Prisons Training School in Kaduna he asked the same contractor to supply foodstuff of N16 million but diverted the checks into his private account.

This led to his arrest nine days ago by EFCC operatives who descended on him in Kaduna.

Egbetokun who was earlier scheduled to report at the EFCC headquarters on Tuesday sought permission to delay his visit until Wednesday as he was attending to official matters.

Detectives quizzed the Speaker after some local government chairmen alleged that statutory allocations meant for their councils were misappropriated by the state government.

Also summoned was the Ogun State Accountant General, Babatunde Salawu, who was questioned on the general financial position of the state and disbursement of local government allocations.

Egbetokun was released while Salawu is being held in EFCC custody for further interrogation.
