Hi Steve
Welcome to TruckNet Uk and I am sorry to hear about your brother.
On this site we do have a forum specially for the family and friends of drivers held in prisons abroad. You can find it here and you may get some help and be able to discuss things with people in the same position as yourself if you also post in there. That forum is sponsered by The Drivers and Families Helpline and you can find their site here.
Good luck
Neil
