Jeremy Vine and Tina Daheley return with a special episode of Crimewatch dedicated to tackling child sex abuse. In light of revelations about the scale of non-recent abuse in football, Crimewatch has been granted unprecedented access to Operation Hydrant, the UK's national police operation tasked with bringing abusers to justice. Specialist detectives reveal how they are investigating these cases, sometimes decades after they took place. The programme also hears from the survivors about the suffering they have experienced and, for some, their sense of resolution when they see their abusers jailed. Jeremy and Tina are also joined by BBC Breakfast's Jon Kay, who broadcasts live from a call centre operating throughout the programme. Offering confidential help and support to victims of abuse, it is hoped this special episode will allow more victims to feel emboldened to come forward and tell their stories.
