In OCHIBA v. THE STATE (2011) LPELR 8245 (SC) where it was held as follows: “I need to say it that it is settled Law that the prosecution was not obliged to call a host of witnesses in order to discharge the burden placed on it to prove the charge against the appellant beyond reasonable doubt as dictated by section 138(1) of the Evidence Act. A sole witness like P.w.1, who has given credible and clear evidence which was believed by the trial Judge, will suffice. See OBUE V THE STATE (1976) 2 SC 141; SADAM v THE STATE [2010] 12 SC (PT.1) 73 at 87-88; AKPAN v THE STATE [1991] 3 NWLR (PT 182) 695”.

But if the cross-examiner intends to contradict the witness by the writing, then he must show the writing to witness and call his attention to those part of the writing which are to be used for the purpose of contradicting the witness. It is only after this condition has been complied with that the writing can be admitted in evidence.”
