Hello I am a solicitor with over 15 years experience. I will try to help you with this.
Am I right in thinking that she has not been arrested for this? Am I also right in thinking that she has been caught once and banned but not referred to the police, She had stolen from other shop without being caught and is worried that now her description has been circulated she will be in further trouble and that the police might be called?
I am on my way to court at the moment but will answer your question when I finish at court hopefully later this morning. I Hope that is OK.
