A top children's writer is suggesting that the boomerang was invented in West Yorkshire rather than Australia.
Terry Deary, author of the Horrible Histories series, got the idea while out jogging on Ilkley Moor and spotted the famous Swastika Stone. The four-armed Bronze Age image is thought by most experts to have been used in the worship of sun or fire. But Mr Deary said: "It's the earliest representation of a boomerang. There's nothing else it could be."
The writer says the first boomerangs would have had four arms as it was easier to get them to return. But over time, the two-armed boomerang was developed. Mr Deary also sees his claim as something of an act of revenge.
"Australians have sent us Rolf Harris and Kylie Minogue. It's payback time," he said.
