Suspected kidnap kingpin, Chukwudumeme Onwuamadike, also known Evans, has pleaded not guilty to two counts of conspiracy and the kidnap of one Dunu Donatus.
Evans was said to have committed the offence in February 2017.
He had earlier pleaded guilty to the two counts during his arraignment on August 30, 2017.
The suspect was arraigned alongside five others; Uche Amadi, Ogechi Izechuwku, Okechukwu Nwachukwu, Chilaka Ifeanyi and Victor Chukwunonso.
While Evans, Amadi and Nwachukwu pleaded guilty to both counts, Izuchukwu, Ifeanyi, and Chukwunonso pleaded not guilty.
But the High Court in Lagos reconvened on Thursday and the amended charges were read to all six defendants.
The prosecution indicated their readiness to proceed with the trial of the defendants and presented three witnesses.
