For a long time, society didn't want to believe child sex abuse was happening - but now are sex crimes against elderly victims being dismissed in the same way?

File on 4 reveals new figures about the scale of alleged sex offences taking place in residential and nursing homes. Whether 5 or 85, should the victims of sexual assault be treated any differently?

Claire Savage hears from the families of elderly people, some with a form of dementia, who have been sexually abused by care workers or by other residents. We also speak to care workers about the challenges they face in dealing with intimacy and sex in care settings.

Experts claim elder sex crimes are being missed or going unreported because not everyone wants to admit these offences are happening. How good are those within the care industry at recognising the signs of elder sexual abuse and at coping with the moral and ethical dilemmas of establishing when a consensual relationship becomes potential abuse?

We speak to those who explain the complexities of bringing about prosecutions where the victim or perpetrator lacks mental capacity and asks if such cases are in the public interest to prosecute.
