Kanu is now championing the reform of the Nigerian judicial system. Kanu was reportedly arrested at the age of 30 and convicted of murder in 1992.
He was subsequently remanded in Port Harcourt Maximum Prisons in Rivers state, while his appeal against the judgement that dragged on slowly.
The case eventually got to the Supreme Court, where he was acquitted of the murder charge on April 5.
While in prison, Kanu reportedly continued his education and obtained Doctorate degree.
Kanu said some of his former fellows in prisons are serving terms for offences they did not commit, hence, his decision to dedicate himself to ensuring a holistic reform of the judicial system.
