By interviewing persons named by this girl, and then interviewing others
whom they in turn named, the police were able, without difficulty, to
obtain admissions and evidence of sexual misconduct by 65 children.

The procedure followed was for the parents to be visited at their
residences by a constable in plain clothes, told the nature of the
inquiry, and informed of the desire of the police to interview the
children at the police station. When a parent and child attended at the
time appointed the parent was informed that, either through a sense of
shame or fear of the parent, the child might not make a full disclosure
of the facts known to her. Some parents consented to their children
being interviewed alone; others desired, and were allowed, to remain for
the questioning. After each interview the parents were permitted to read
the statements of their children and to sign them before the children
themselves were asked to sign.

The disclosures thus made, immediately recalled certain similar
occurrences in the same district during October/November 1952. It
speedily became apparent that the 1954 situation was much more serious
in that there were approximately three times as many children dealt with
and that three of the children had been involved in the earlier trouble.
