Obviously the jury was also unaware. But this is the law. Previous criminal convictions and investigations cannot be mentioned during trials. This would influence juries to convict people on "previous", rather than the facts of an individual case. In other words, it prevents the police from fitting up a known criminal in order to meet crime solved/conviction targets.
I agree with this, to a degree. But serial rapists, paedophiles and various other scum are benefiting from this fairness.
