The legality of a situation like this can vary depending on the jurisdiction and specific circumstances involved. However, in many places, harboring or hiding a runaway minor can potentially lead to legal consequences for the adults involved.
When a minor leaves home without the permission of their parents or legal guardians, they are considered a runaway. In such cases, the parents or legal guardians might report the runaway to the police, who may then investigate and try to locate the minor to ensure their safety and well-being.
If the friend's parents are aware that the minor is a runaway and knowingly provide shelter or assistance without informing the authorities or the minor's parents, they could be accused of harboring a runaway. This act may be against the law in some jurisdictions and could result in legal action, such as facing charges or fines.
It's important for all parties involved to prioritize the safety and well-being of the minor. If a friend finds themselves in such a situation, it's best to involve a trusted adult, such as a parent, teacher, or counselor, who can help address the situation appropriately and in accordance with local laws.
