A spokeswoman at their Warwickshire headquarters said the advice was given to try to ‘maintain goodwill across the showground’.
However, she said that her child would be welcome at forthcoming events.
The British Show Jumping Association (BSJA) have also confirmed that the talented young rider will not be barred from competing while the police conduct their inquiries.
It has been announced that the child will be able to compete when the local branch of the BSJA holds a rerun of its show jumper of the year competition on 23 September.
