How do I contact/find the Judge in this case?

[SilenceOfTheSAHMs]

I have vital information that I wish to impart to the Judge in a case of burglary. I wish to write the Judge a simple letter stating these facts. It is a Crown Court case.
Believe me, I do not often involve myself in such things (far too busy with DC's and work!) but I cannot see someone who has repeatedly stolen get away with "Murder" as it were.
Do I ring up the relevant courthouse?
Please can someone advise their experiences in this?
Have to go towork but will be back this afternoon, Many Thanks.

advise ON their experiences

Why can't you phone the police, so they can take a statement and include it in their evidence for the CPS?

Yes, surely you report it to the police.

You need to tell the police.

You cannot contact the judge directly at this stage. The police will present your evidence to to the judge, and it'll move from there.

Thanks everyone, I shall contact the Police, just was unsure of how to go about things thats all.
