The Economic and Financial Crimes Commission, EFCC, has released the detained former Secretary to the Government of the Federation, Babachir Lawal.
A source in the commission told the News Agency of Nigeria that Mr Lawal was released on administrative bail on Friday evening.
The source, however, did not give further details.
Mr Lawal was detained by the EFCC on Wednesday morning after he honoured an invitation to the commission’s head office in Abuja.
When NAN contacted, the acting spokesman for the commission, Samin Amaddin, said he was not aware of the issue.
The development followed Mr Lawal’s sack by President Muhammadu Buhari on October 30.
Mr Buhari’s action was based on the recommendation of a presidential panel that probed misuse of funds meant for Internally Displaced Persons, IDPs, in the North East.
The former SGF is accused of using his company Rholavision Engineering Ltd to corner a N200 million contract for the clearing of “evasive plant species” in Yobe.
