It is believed that Emenike agreed to miss a match against Fenerbahce in exchange for a £9million transfer to the Istanbul giants, which brought about a stay in prison, despite Karabukspor producing a doctor's certificate to prove he was unfit to play.
Emenike told The Sun: "My time in prison was a crazy nightmare that I couldn't wake up from.
"I've never committed a crime in my life but I was treated like a criminal, living on bread and water.
"It was not a good experience. It gave me a different perspective on life."
He added: "When I was finally cleared I thanked God for letting justice prevail."
