Director of the NSPCC helpline Peter Watt said:
We are assisting the police on Operation Fernbridge and are asking anyone with information to come forward.
We will assist the police in gathering evidence and supporting those who come forward.
It's important we recognise the massive impact abuse has on children and young people, often well into their adult life.
- The NSPCC's 24-hour helpline, which is staffed by trained counsellors, is available by emailing firstname.lastname@example.org or via text message to 88858.
