Hamisu Bala (alias Wadume), a suspected kidnap kingpin, and five others have been arraigned in court.
Wadume and four others are facing charges bordering around kidnapping and murder, including that of three policemen and a civilian killed at a checkpoint in Taraba State.
Some soldiers had last year opened fire on policemen, who were conveying the alleged kidnap kingpin following his arrest.
This led to the death of three police officers and a civilian and also allowed Wadume escape from custody.
Following his rearrest in August 2019, the suspected kingpin was charged with terrorism and murder by the Nigeria Police Force in February 2020.
The Office of the Attorney-General of the Federation on Tuesday formally took over the prosecution of the case from Mohammed Adamu, the Inspector-General of Police.
However, only six of the 20 defendants, including Wadume, were present in court on Wednesday.
The 10 soldiers among the defendants were absent on Wednesday, a repeat of the scenario when the case was first mentioned in court on 16 March.
Labaran Magaji, the prosecuting counsel from the AGF office, requested an adjournment to enable him to make moves for the production of all the defendants in court.
Magaji explained that his office took over the case and received the case file from the police on Tuesday.
He said: “The AGF office applied to take over the prosecution of the criminal charge. We were handed over the file yesterday(Tuesday). The case has about 20 defendants, but only six defendants are present in court.
“The prosecution shall do the needful to ensure that the case takes off immediately.”
Defence lawyers that were present in court did not oppose the request for adjournment.
Justice Binta Nyako, the trial judge, adjourned the matter till 8 June.
