When Rowena and Jack Churchland sat down to watch footage from the video camera they had installed in their son’s nursery they expected to find nothing of particular concern.
They had, after all, only put it there as a precaution, hoping it would give Rowena peace of mind after she had, reluctantly, appointed a nanny to look after their precious son one day a week while she returned to work in the family business.
Instead, what they saw on that chilly January Saturday night horrified them. There, captured with dreadful clarity, was their 18-month-old son being assaulted by the woman they had trusted to care for him.
For nearly an hour, restless in his cot over what was meant to be his lunchtime nap, Olly received no loving words or reassurance.
Instead, he was manhandled several times by his stonily silent nanny before being picked up, flung roughly against the mobile hanging above his cot so that he banged his head, and smacked hard on the bottom three times, making his body shake.
