The accused, Paul Okeke, Chinedu Egwu and Solomon Onah, are standing trial on a two-count charge bordering on drug trafficking.
The Prosecutor, Orji Kalu, had told the court that the trio committed the offence on July 3, 2013.
He said that the accused were unlawfully in possession of 50g of cocaine.
Odede told the court that the accused were brought to him with some white powdery substance suspected to be cocaine.
He said that the trio confirmed that the substance was recovered from them.
Odede said some forms were issued out after the substance was tested, adding that they were the certificate of test analysis, parking of substance form and request for scientific aid form.
The prosecutor tendered them to the court and they were admitted in evidence.
Counsel to the accused, Mr O. Ojakovo, cross-examined the witness, to ascertain if he was among the officers that arrested the accused.
The prosecutor urged the court to adjourn the case, to enable him call other witnesses.
Justice Chukwujekwu Aneke, however, adjourned the case till July 7, for continuation of trial.
The News Agency of Nigeria (NAN) reports that the accused were first arraigned on Oct 24, 2012 but were granted bail.
The case was before retired Justice B. Molokwu, before it was transferred to Aneke.
A drug trafficking offence could attract life imprisonment, if convicted. (NAN)
