A Lagos Division of the Federal High Court had on Tuesday ordered the immediate release of Kalu from the correctional centre.
Mohammed Liman, the judge, granted an application moved by his counsel Lateef Fagbemi seeking his release.
The Economic and Financial Crimes Commission did not oppose the application.
The former governor had urged the court to set aside his conviction on December 5, 2019 by Justice Mohammed Idris.
He explained that this became necessary since the Supreme Court in its verdict delivered on May 8, 2020, held that Justice Idris gave the judgment without jurisdiction.
