My dad is undergoing an extradition trial for fraud. I recently found out he has frauded me and opened credit cards in my name. Can I give this information to the investigation or is it empty? [ENGLAND]

He is currently undergoing a trial consisting of 36 counts of fraud. Am I able to give my evidence to the case to add that is he is still actively frauding people. Or is that not allowed as I’m “irrelevant” and identity theft isn’t a direct crime against me.
thanks!
