Where there is a risk of harm or actual harm to a vulnerable person – e.g. a child, someone with mental ill health, old age, frailty or physical disability, visual or hearing impairment you have a duty to report to the local authority / social work. If a crime has been committed – e.g. theft, violence, you have a duty to report to the police.
