Thanks Yorkie......Will they have the nationality of offenders? Or just where they lived at the time of the offence?
I don't know the answer to that but you should ask your question detailing all the different criteria you wish to be answered.
Rather than writing direct you can do this through the web site "What do they know" at
http://www.whatdotheyknow.com/ either using your own name or an alias. The information then becomes available to anyone. If you search for Llandudno and Conwy you will be able to see what questions have been asked in the past. ££$
