Several sources, including CBBC Newsround, report this:

"A man walking in Suffolk has reportedly stumbled across the ultimate treasure - two top secret copies of Harry Potter and the Order of the Phoenix.
The fifth book in JK's series isn't out until 21 June and the manuscripts of it are closely guarded.

But the first edition copies were found lying in a field near to the printers Clays Ltd, the company which will print hundreds of thousands of the much-awaited book says the Sun newspaper.

The man, who was walking near the town of Bungay, realised what he had discovered and telephoned the newspaper straight away.

He told them: "I wondered what it was and bent down to pick it up. I was astonished when I read the first page and saw it was the latest Harry Potter book."
He couldn't believe his eyes and wondered why no one else had spotted them.

The copies had no covers on them, but on the first page of each copy was the title and JK's name.

The newspaper says it sent two of its journalists to pick them up.
And they say they have contacted Bloomsbury to return the books and refuse to let anyone know what's in them!

At the moment, the newspaper says it has locked the precious copies away in a safe place.
But they claim a third copy could have been leaked out.

They say they were offered the first three chapters of the OOTP for a large amount of money, but they refused the offer."

The Sun article contains a picture of the purported copy.
