Joanne Riggs was a social worker called in by Anna Windass when her adopted daughter Faye made contact through the internet with her natural father Tim Metcalfe after many years apart. Anna was concerned as she knew nothing about Tim though, in truth, her main concern was the girl could be taken from her. On Joanne's first visit she put Anna's mind at rest by saying that legally Tim had no legal or parental rights over his daughter but they were powerless to stop Tim seeing Faye until they had carried out a full risk assessment on him.
