Based solely on the information you have given she was not arrested and will not have to go to court. Beware, however, of paying the store what it might call a fine or a civil demand. If you pay you go into the National Retailers Data Base which will prevent your ever getting a job in retail.
If you are not arrested you will probably not be. You can usually ignore the letter from the lawyers demanding the civil fine and if you pay it there will be a record of that. The real issue is that people who shoplift are very bad decision makers and usually young people who act on impulse without considering the consequences so they must be taught morals if not sophistication and get a good education before it is too late. That takes thousands of hours of hard work and study and that is why most people never bother to acquire that knowledge and those language, career, and people skills. For the rest of their life they make poor decisions and do not become successful as they lack the skills and knowledge to become successful. That is the "problem" not the shoplifting.
