This is an unfortunate situation.
Generally if the child leaves the court ordered residence, he will be a run away and police reports will be generated. If you do not force him to return then you will likely be hit with contempt orders and the police will be unhappy with you. Yes, people have been charged with violations about these sort of issues.
If the order is more than 2 years old it can be brought back into court, but it must be in the best interest of the child. A problem child is not going to be viewed positively when making that request.
Sorry your having these problems.
