Sounds like your child was under 17 and thus was taken before a magistrate before being questioned which is the proper manner in which to handle such matters by police. They do not have to notify you of their intent, nor allow them to call their parents. Parents are to be notified afterwards. The interviews are recorded so if Miranda rights were not given and the person was a suspect, any inculpatory statement can be suppressed. If they have been charged, they need lawyers. They can be told that in the future they do not have to cooperate with the police if interrogated and they have the right to request a lawyer.
