Manus Provincial Police Commander, Chief Inspector David Yapu, said most of the offenders were charged for minor offences whilst four were for indictable offences.
He said they could have used hacksaw blades to cut the iron bar and made their escape from the cell.
So far, three have surrendered to Police, including a murder suspect.
PPC Yapu, who was frustrated over the escape of the prisoners, had directed his Police Station Commander to investigate and take appropriate actions.
