The predatory entertainer was used as a reassuring and trusted figure

The predatory entertainer was used as a reassuring and trusted figure to introduce infants to “what a child needs to know about strangers”.

Published in 1985 – at the height of his fame as Jim’ll Fix It presenter – twisted Savile warns primary school children of the explicit dangers of talking to people they don’t know.

Millions of teachers and parents who used the book were unaware Savile had embarked on a decades-long campaign of rape, sexual abuse and molestation against his young victims.

Chillingly, the perverted Top Of The Pops host says: “Will you remember a stranger is danger when you are on your own? Will you remember the stories in your book? I hope so because I like you and want you to be safe and happy. Best wishes from your friend, Jimmy Savile.”

The hardback book Stranger Danger, published by Hamlyn, used the travails of Benjamin Rabbit to help infants understand they should never accept sweets or lifts from strangers.
