However, no sooner had the judge ruled than Kanu indicated his interest to talk.
He told the court that he decided to go underground because his house was raided, but he could escape.
Kanu said if he had not escaped, he might have been killed like other group members.
The judge, who advised him not to feel discomfiture to stand his trial, urged him to get across to his lawyer for the trial.
The News Agency of Nigeria (NAN) reports that Kanu was arrested on Oct. 14, 2015, on 11 count charges bordering on terrorism, treasonable felony, managing an unlawful society, publication of defamatory matter, and illegal possession of firearms and improper importation of goods, among others.
