He claimed that he was forced to admit being a kidnapper after the police killed four individuals in his presence in order to compel him to confess to the crime.
He said: “I live at Fred Shoboyede Street, Magodo Phase II, Lagos.
“My lord, my name is not Evans and I don’t have a nickname.”
Onwuamadike also denied knowing his co-accused, Uche Amadi, Okwuchukwu Nwachukwu, Ogechi Uchechukwu, Chilaka Ifeanyi and Victor Aduba, saying he saw them for the first time in the day they were paraded by the police at Area F Police Command, Ikeja, Lagos, as members of a kidnap syndicate.
According to the prosecution, Mr Dunu was kidnapped on Ilupeju Road, Lagos and the defendants allegedly collected 223,000 Euros as ransom from his family before he was released.
All the defendants during the criminal trial have insisted they were innocent.
Justice Oshodi gave the defence 30 days to file their final written addresses and the prosecution another 30 days to respond to the defence addresses.
The case was adjourned until November 5 for the adoption of the final written addresses.
