The Economic and Financial Crimes Commission on Friday night released a former spokesperson to former President Goodluck Jonathan after keeping him in their custody for about 12 days.
Abati told Ripples Nigeria on phone shortly after his release that he is doing fine.
Abati was taken into custody on October 25 by the anti-graft agencies on allegations of having received N50 million from embattled former National Security Adviser (NSA) Sambo Dasuki.
Sources at the agency had then said that Mr. Abati admitted receiving the money from Dasuki and explained how he spent it.
Mr. Abati reportedly told investigators that he spent the N50 million on media relations that had to do with his work as media adviser for Mr. Jonathan.
But when asked for evidence of how the money was spent, he reportedly said media relations details were never documented.
