In the situation where there is legitimate concern that a child is being mistreated or abused, in everyday life (or cultic situations) they are obligated to report that to the local child protective authorities.
If a person is a teacher or medical authority, they are literally obligated to file a report.
Then the local authorities have to look into it.
If a person has knowledge of a child being mistreated, then its a moral duty to file reports with the local child protective services, and the police, local politicians, and everyone else until someone in authority listens and investigates.
