Ella Clarke and her brother Mason, from Old Catton, Norwich were riding their motocross bikes on Saturday at Wildtracks Activity Park by the A11 near Newmarket before going inside their caravan.

But while they were not looking, their bikes were stolen.

Kaysie Davidson, the children's mother, said: "They were absolutely heartbroken.

"They were supposed to ride again on Sunday which is why we were camping, so not being able to ride and watching their friends clearly upset them."

Both the bikes were taken........
