A thief seized a copy of the new Harry Potter book after its owner took his eyes off it for a moment.
Chris and Alison Foster had bought the book for their 11-year-old son Matthew, a big Potter fan.

It came complete with a gift pack, including Harry Potter playing cards, in a special bag.
But before Matthew had a chance to get his hands on it, it was stolen.
Mr Foster, 50, had been sitting near Queen's Lane, High Street, Oxford, with the book between his feet waiting for Frederick Tranter's Tobacconist, where he works on Saturdays, to open on June 21.
As he stood up he realised the book, Harry Potter and the Order of the Phoenix, had gone.
His wife Alison, 41, said: "We had pre-ordered it from Waterstone's and they put it in a distinctive bag so it was clear what was inside."
Mrs Foster, of Marston, Oxford, said: "Someone just swiped the bag. I just hope they can live with themselves, whoever they are."
The couple were able to buy another copy of the book, but said they were disappointed that Matthew would miss out on the extras. Mrs Foster said: "I feel awful for my husband as he feels very responsible and was very upset."
